London will host the 2012 Olympics after winning the International Olympic Committee vote in Singapore.
London beat Paris in the final vote after Moscow, New York and Madrid were eliminated in the first three rounds.
Our reporter in Singapore, Andrew Fraser, other BBC journalists and key participants in London's success gave their observations and reactions throughout a remarkable day.
REACTION TO LONDON GETTING THE 2012 OLYMPICS...
1630 BST: Ken Livingstone, Mayor of London
It's a wonderful evening here in Singapore and it has been incredible here with the whole team concentrating on winning. The East End never really recovered from the collapse of the old docks and industry and we're determined that the new shops and homes are coming for the people who live in the area. It has been an emotional rollercoaster. I can't think of any other leader who would spend three days here lobbying delegates. Tony Blair subordinated his position to be part of this team and then there was Seb Coe who has been a fantastic team leader and gave an incredible presentation. Thirty years ago he was a raggedy arsed little boy with no real prospects in life and the Olympic movement gave him everything he has become. That was the message we had. It was not just about regeneration but kids achieving their personal best.
1627 BST: James Pearce, BBC News, Singapore
The London people are very tired. They've been here more than a week working tirelessly, but the win means there was no wasted effort and they will party. It was desperately close but everyone is agreed two things swung it for London - the Prime Minister's visit to Singapore and Seb Coe's presentation.
1615 BST: Shirley Robertson, double Olympic champion
We've had a few glasses of champagne here at the IndoChine. This party will go on for a while and I'm a bit worried about catching my flight in the morning. It hasn't sunk in yet, you just have to look at Seb to realise that. He has been a wonderful leader and he and his team have been in a focused state making sure they had the best bid and they did.
1610 BST: Victoria Derbyshire, Radio Five Live, Singapore
I'm at the IndoChine restaurant where the London team are celebrating. It's a spectacular setting overlooking the Singapore River on a balmy night and everyone is in a terrfic mood. Seb Coe has just arrived and was given a huge round of applause. He is now addressing the throng to even more applause.
1608 BST: Andy Swiss, BBC Radio Five Live, Singapore
I'm still at the Raffles complex - it's the calm after the storm with just a few shellshocked looking journalists hanging around. The Paris team have gone off to drown their sorrows and London are set for an almighty party across town. The presentation made London stand out from the crowd, it was more aggressive than the others. It said you've got to be brave and pick us.
1521 BST: Daley Thompson, former Olympic champion
I've been so confident. We've sold ourselves so well over the last two years. This is an opportunity of a lifetime for our country and we can change the landscape of health and fitness among kids.
1512 BST: Jon Sopel, BBC News, Paris
The stage that was supposed to play out the celebratory party is being dsismantled.
It was a surreal moment of shock when the result came through and while most people have left there has been a gaggle of people locked in an argument ever since. Was it all politics, were there other issues and they're trying to explain conspiracy theories to each other? When Trafalgar Square was shown on the big screen everyone started booing and it's hard to broadcast as people left outside the Hotel de Ville are very upset.
1506 BST: Tessa Sanderson, former Olympic champion, Stratford
Everyone said Athens wouldn't be ready but they were. I have no doubts we'll be ready on time and we'll put on a fantastic Games. This is going to be fantastic for the East End and Stratford is buzzing. It will leave a fantastic legacy.
1453 BST: Ben Brown, BBC News, IndoChine Restaurant, Singapore
This is where the London bid team are having their party and there are people here who have devoted months and years of their lives to winning the 2012 Olympics. Some big stars will be here at this party and David Beckham and Sven-Goran Eriksson are just arriving. They will be joined by plenty of Olympic champions in the coming hours and the bid leaders.
1447 BST: Barbara Cassani, former London bid team leader
I'm incredibly proud. I was sure we had a winning team and I'm proud of everyone. This proves standing down was the right decision. We needed a British person and someone from sport in charge and the combination of Seb and Keith Mills was strong.
1437 BST: Gordon Farquhar, BBC Radio Five Live
The things that stands out for me is that the gamble the bid took in pitching their presentation to the future clearly worked, IOC president Jacques Rogge admitted as much. They worked out what the IOC wanted to hear. The strange thing about today is that after 14 hours on air I'm not sure where the party is. There will be huge parties and no doubt there will be a London party and that is the hot ticket, the one I want to go to.
1431 BST: Sir Matthew Pinsent, four-time Olympian
Even at the end it was only four votes. You only needed the Prime Minister to have done a few meetings less, or for someone to slip up at the presentation or for others to have missed a few chance encounters and we would have lost. We are shocked but ever so proud.
1419 BST: Chris Hollins, BBC News, Stratford
It's all about partying here and there is a fantastic atmosphere in Stratford. They cannot believe the Olympics are coming here. This will put Stratford on the map and leave a lasting legacy for the area.
1406 BST: Saj Chowdhury, BBC Sport at Trafalgar Square
People are slowly filtering away now but in reality the party has just begun as a Rio style carnival hits the square with drums and dancers in bright costumes. French woman Emile Maupassant, from Lille, reflects: "We did not send any stars to Singapore and that's why we lost. We were too arrogant. Bonne chance Londres!'
1300 BST: The Princess Royal, Princess Anne, IOC member
My ambition today was not to have to vote and I'm glad that was fulfilled. The end result was amazing. We always knew this was going to be a close result - you cannot have five cities of that quality without a close result. It has been a wonderful occasion for the Olympic movement and I know London will make the IOC proud of their decision.
1355 BST: Jacques Rogge, IOC president
We are very pleased with the victory of London. It was a high quality bid and they are people we trust who will deliver a great Games. We know the cruelty of sport, but this an even crueller game with only one medal - a gold one. Well done to London.
1325 BST: London sign the host city contract.
1349 BST: Dame Tanni Grey Thompson, British Paralympic legend
This is huge. Great Britain has a fantastic reputation and this will set the world on fire. We'll have a good Olympics and a a great Paralympics. What we have to do now is make sure the grass roots are right and that we put on a good show.
1344 BST: Saj Chowdhury, BBC Sport at Trafalgar Square
In an address on the big screen Tony Blair told the crowd in London "well done". Listening were a group, who work for a design agency who have helped with the bid, wearing cut-out Seb Coe masks. One of them, Matt Akex said: "We've got a day off workso I think we'll have a few drinks". Not all shared the sense of elation. Vannessa Fristetd holding a 'No to London' placard said: "I believe it will turn out for the worse.I think this is bad news".
1336 BST: Jacques Chirac, French President - in a statement
London - Good luck in staging the 2012 Games.
1333 BST: Tony Blair, Prime Minister
This is a momentous day for London. It's a great chance to develop sport and leave a legacy for the future. It was genuinely a team effort and Seb Coe and the team were just awesome throughout. For me it was easy coming in with the way that Seb and his team worked. They were focused and clever in every single aspect. It really shows what you can achieve if you work together. I couldn't bear to watch the final bit. I've been trying to work on the G8 stuff but my mind has been in two places today. I went for a walk and got a call from the switchboard. It's not often in this job that you punch the air and do a little jig and embrace the person next to you. It's a fantastic thing and I'm thrilled.
1327 BST: The Queen, in a message to Lord Coe
I send my warmest congratulations to you and every member of the London 2012 team for winning the bid for the UK. It's a really outstanding achievement to beat such a highly competitive field.
1320 BST: Katya Adler, BBC News, Madrid
The crowds have now gone but they hung around for the final decision. When Paris was mentioned it received huge boos. But Plaza Mayor went wild with delight when London won and they went crazy when they saw Real Madrid's David Beckham celebrating on the big screen. They're sad they did not get the decision but are happy London won the vote.
1318 BST: Jon Sopel, BBC News, Paris
You could feel the atmosphere drain away from the crowd that had gathered outside the Hotel de Ville. Everything was in place for Paris. What could go wrong? Well, absolutely everything. They've lost to the old enemy and this will add a piquancy in the relationship between Tony Blair and Jacques Chirac in the coming days at the G8 Summit at Gleneagles.
1314 BST: Tessa Jowell, Olympic minister
I've been shaking for the past two hours. This is the biggest prize sport can bestow and we won it for London and this is to unlock the ambition of children. Sport will now be central to government policy.
1310 BST: Richard Caborn, Sports minister
While London has won it this is for the whole of Great Britian. We were very concerned because all the photographers were around the French delegation. When Jacques Rogge opened the envelope I've never heard a sweeter word in my life. London will have a games to make us proud. It's fantastic.
1307 BST: Ken Livingstone, Mayor of London
This is amazing. When we started out it was a mountain to climb, but we've had an incredible few days here. What came over in our presentation was giving kids the chance - it's not just about cities. We spent a lot of time before formally submitting our bid preparing things and we will start work on that tomorrow. We'll give the world the best Games they've ever seen. We only had about four jounalists in front of us and Paris had 50 in front of them so we thought they'd been tipped off. We assumed we had lost.
1300 BST: Lord Coe, London bid team chief
It's just the most fantastic opportunity to do everything we always dreamed of in British sport. We can change the face of sport in the next seven years... and beyond. This was a splendid team performance from two years ago when the team came together and everyone pulled together. We never lost confidence.
1257 BST: Danny Crates, Paralympian, Trafalgar Square
We'll do this better than anyone and we're more passionate about Paralympian sport than anyone else. I was shaking and felt sick, but when they said 'London' it was a brilliant feeling. It was deserved and a quite brilliant bid.
1255 BST: Dame Kelly Holmes, double Olympic champion, Trafalgar Square
This is incredible. I'm really emotional and I don't know what I did when they announced 'London'. This will do wonders for the country. We came from the back and proved we wanted it and this will change the face of Great Britian forever.l
1253 BST: Alan Robb, BBC Radio Five Live, Paris
There is utter disbelief at the Hotel de Ville. Initially it was shock and after an intake of breath from thousands of people the crowd started booing. People are really not happy and are now leaving the square. There is bitter disappointment here.
1252 BST: Saj Chowdhury, BBC Sport at Trafalgar Square
People are stunned as a wave of cheers carried through the square as some appeared to hear the result before others. The mood is one of enormous elation.
1250 BST: Gordon Farquhar, BBC Radio Five Live
The London team have gone absolutely ballistic here. There are extraordinary scenes in the ballroom with all the emotions you'd expect. The Paris team are understandably disappointed but all the focus is on the London team who are celebrating hosting the Olympics for the first time since 1948.
THE BIG DECISION...
1249 BST: Jacques Rogge opens the envelope and declares LONDON will host the 2012 Olympics.
1242 BST: Saj Chowdhury, BBC Sport at Trafalgar Square
It is starting to rain - hope it isn't an omen. It's impossible to move as everyone has come out for their lunch. It seems like most of London is down here.
1239 BST: Emily Maitliss, BBC News, Stratford, London
This is the most emotional part of Britain today because the people here will have their lives touched more than anywhere else in the country. It would mean a massive change for Stratford. Whereas the sexy headlines have been about archery at Lord's or whatever, Stratford is where the real story is. Stratford has been put on the map by this bid and is now known as 'Beckham's manor' after his comments supporting the campaign. This will not be some kind of flat-pack games, it will inspire a generation.
1235 BST: Dame Kelly Holmes, double Olympic champion, Trafalgar Square
I'm very nervous and feel quite sick. Whatever happens we've put in a brilliant bid and have done ourselves proud. The support here is absolutely marvellous. If we get the Games it would change the whole of Great Britain and leave an excellent legacy. The Olympic movement and spirit stays with you for life and it would change everyone's perceptions on sport.
1233 BST: Nigel Adderley, BBC Radio Five Live, Paris
It is incredibly tense outside the Hotel de Ville. Hundreds of people are now crowding round radio stations broadcasting into the open air trying to find out the latest news.
1230 BST: The final part of the decision process formally gets under way.
REACTION TO THE INITIAL VOTE...
1224 BST: Gordon Farquhar, BBC Radio Five Live
The ballroom in the Raffles Convention Centre is filling up and the Paris delegation are looking relaxed. The London team are further away and it's difficult to pick up any reactions from them. Virtually every seat is full now and the IOC delegates are all in place.
1215 BST: Andrew Fraser, BBC Sport in Singapore
A large crowd is beginning to gather as the excitement builds towards the final decision which is now just half an hour away. Members of the media are frantically looking for any clues in body language from the great and the good - but to no avail. That said, you don't need to be much of a detective to guess what is going through Yuri Luzhov's mind. The Moscow bid team member walks by stony faced with a mobile phone pressed to his ear.
1211 BST: Former Olympic champion Daley Thompson
I'm feeling relaxed. We've done a good job, it's out of our hands and I think we've won.
1210 BST: Simon Clegg, British Olympic Association chief executive
It's fantastic. We always believed we had a winnable bid and now we're up against Paris. I can't wait for the president of the IOC to announce the winner and I'm really confident about London. There's nothing more we could have done and I genuinely believe we're going to pull this off.
1206 BST: Andrew Fraser, BBC Sport in Singapore
Journalists rush across the hall after a crowd start chanting 'Paris, Paris', but it is only over-zealous celebration at reaching the last two and not an indication of who has won.
1159 BST: Gordon Farquhar, BBC Radio Five Live
There's a real buzz here in Singapore. London bid member Keith Mills says "it's in the lap of the Gods", but adds this is what he wanted.
1157 BST: Nigel Adderley, BBC Radio Five Live, Paris
Thousands of people were on their feet when the result came through with Tricolores waving everywhere. There's a growing belief Paris are going to do it and the cheers here have got far, far louder as the morning has progressed.
1153 BST: Andrew Fraser, BBC Sport in Singapore
Nobody knows the result of the vote but the Paris bid delegation are all smiles in the area outside the hall and there are a few pats on the back. London's team walks past moments later and Olympic minister Tessa Jowell says she has "absolutely no idea" who has won, adding "it's all very nerve-wracking".
1148 BST: Former Olympian Sally Gunnell, Trafalgar Square
What a relief. London did a great presentation, I thought they were very clever in bringing out the key issue which is children, because children are the future of the Games. That last 45 minutes this morning has made a key difference and I'm keeping my fingers crossed. My gut instinct is it is very very close and hopefully we can win. We've done our best and all we can do is wait.
UPDATES FROM THE VOTE...
1144 BST: Andrew Fraser, BBC Sport in Singapore
There are a few gasps in the press room as Madrid exits the vote, as some Spaniards at the back had earlier given some noisy support during its bid presentation. We now have the London-Paris finale that the whispers in the past few hours had indicated.
1136 BST: Madrid is the third city to be eliminated.
Matt Williams, BBC Radio Five Live, Madrid
Disappointment, shock and surprise - those are the feelings here. They were chanting 'A Madrid' before the announcement but that has now changed and I can't repeat what they're saying now.
1132 BST: New York is the second city to be eliminated.
Laura Trevelyan, BBC Five Live, New York
They're looking disappointed in the Rockefeller Centre after that. The impression I got was that New Yorkers were not persuaded this was the best city to hold the Olympics, but that will not prevent a feeling of disappointment.
1128 BST: Moscow is the first city to be eliminated.
The thousands in Red Square have not heard the news yet and it will spoil the party. It may not be much of a surprise for most of the world but it will be a great disappointment to the people of Moscow and Russian officals who have put a lot into the bid.
Steve Rosenburg, BBC Five Live, Moscow
1124 BST: Voting finally starts.
1117 BST: Nigel Adderley, BBC Radio Five Live, Paris
People now look very bored as they watch the IOC try to vote. There are several hundred people in the square but with dark clouds overhead, it's not packed. Boos were heard when London was drawn out for voting. There were huge cheers when Paris was allocated a voting number.
1114 BST: The cities are all given a corresponding number - three for Madrid, eight for London, four for New York, nine for Moscow and seven for Paris - but yet more explanations mean voting is yet to start.
1108 BST: Andrew Fraser, BBC Sport in Singapore
It's a slow start. Members are being told how to operate their electronic voting boxes. Confirmation of the vote will remain on the screen for a few seconds and then disappear. After that, it will be too late to change their minds, at least for that particular round. Just to check everything's working they have a practice with famous painters instead of cities. Leonardo Da Vinci beats off competition from Botero, Magritte, Van Gogh and Fujita.
1100 BST: Jacques Rogge announces the start of the voting procedure.
NEWS FROM THE COUNTDOWN TO THE VOTE...
1053 BST: Gordon Farquhar, BBC Radio Five Live
All the feedback I'm getting suggests it's down to two bids, London or Paris. It's a challenge for the IOC. Do they stay with the safe bid, which is Paris, or go with the new one with momentum, London?
1044 BST: Saj Chowdhury, BBC Sport at Trafalgar Square
Pop star Heather Small is performing on a stage next to the fountain. Earlier in the day people were out-numbered by pigeons, but now it's beginning to swing the other way with about 300-400 people milling around, including lots of school kids who assure me they are genuinely allowed to be here and are not skipping lessons.
1036: Laura Trevelyan, BBC Five Live, New York
It is not even 0600 local time but there are at least 100 people in the Rockefeller Centre all getting very excited at the thought that the voting is soon about to start. Some people have stayed through the night after coming to watch the presentation on a big screen here last night.
1030 BST: Jacques Rogge announces that the start of the vote has been put back 15 minutes to 1100 BST.
1027 BST: Steve Rosenburg, BBC Five Live, Moscow
I'm standing opposite a giant stage and screen in Red Square and it has been pretty empty all morning bar for a couple of hundred soldiers. But in the last five minutes thousands have arrived in a very un-spontaneous sort of way. It is a great back drop to what they hope will be a great party.
1025 BST: Andrew Fraser, BBC Sport in Singapore
"This is not easy," was the line from one IOC member as he chatted to a colleague after Madrid had completed the last of the five bid presentations. The men and women who will decide the host city for 2012 clearly have some hard thinking to do with just 20 minutes to go to the big vote. The Daily Telegraph's experienced Olympic correspondent Mihir Bose predicts a final-round showdown between London and Paris, with the votes up for grabs if Madrid drops out likely to decide the contest. "It could be Paris by seven or eight or London by two or three," he says.
Suggestions of tension between the Paris and Madrid bids have surfaced after Prince Albert of Monaco asked a potentially damaging question about the Spanish capital's terrorism problems after its presentation. IOC chief Jacques Rogge warns his members to take their seats quickly for the report of the evaluation commission on the rivals. "We're starting to run late," he says.
1015 BST: Jonathan Edwards, Britain's former Olympic triple jump champion
We've had a tremendous response from the media but it's the IOC members who count. The sense of euphoria after the presentation should not convince us we've got it in the bag, but if we can get through the third round into a head-to-head we're confident of winning.
1009 BST: Nigel Adderley, BBC Radio Five Live, Paris
The square by the Hotel de Ville is filling up with school children all wearing 2012 T-shirts on a chilly day in Paris. The French papers are full of how the English media attacked Jacque Chirac's comments about our food. France Soir newspaper calls it "the war of the grub" saying that "the knives aren't just out for the President, the forks are too!"
0946 BST: Matt Williams, BBC Radio Five Live, Madrid
I'm in Plaza Mayor in the heart of Madrid and for a city that is through to the last five of the Olympic vote there is not a huge amount of enthusiasm, especially for one with a 91% approval rating. There's only a couple of 100 people here and from the scenes I've seen, Paris and London are getting into the swing of things much more than people are here.
NEWS FROM AFTER THE LONDON PRESENTATION...
0923 BST: Sir Bobby Charlton, London bid team member
There's been a great buzz all week. The presentation raised all the issues that were important to the IOC members and London came up with all the answers. It's the best bid and it would be unbelievable if we didn't win it. We're so superior and it's the right time for London to host the Games. I've never felt so close to the great prize. Now I'll be biting my finger nails until the vote and doing my best to have a word with any IOC members.
0900 BST: Andrew Fraser, BBC Sport in Singapore
There were some big smiles as London's bid delegation left the main hall after making a powerful case to host the Games, with one French journalist remarking: "I hope the Paris team didn't see that." Asked if they had felt IOC members warming to the presentation, London bid
number two Keith Mills joked that he thought he "saw a little tear on the
way out". British IOC member Craig Reedie said he thought perhaps 15 to 20 votes might still be in the balance.
As for 14-year-old Amber Charles, who sat on the top table with Lord Coe and his key team members, she admitted she had feared she might trip over on the way to the podium. Coe signed off his news conference by saying: "I wouldn't swap the situation we are in. This team has gone the extra mile and I hope it's enough." With that, it was off to watch the final presentation from Madrid, with the vote less than two hours away.
0841 BST: Four-time Olympian Matthew Pinsent talks to BBC Five Live after the presentation
We have a trump card in that we have an Olympian leading our bid. The videos worked well, but Seb Coe is such the consumate presenter. It was a well-rounded presentation and there were always strong messages coming out. We've given ourselves the best possible chance to win. We've done what we can and I walked out with goose bumps. Half a dozen IOC members have come up to me saying it was the best presentation, but is that an accurate representation?
0828 BST: Former Olympic athlete Kriss Akabusi, Trafalgar Square, London
I've got a feeling Nelson is going to be jigging come 1250 BST. Big Ben is going to be clocking a little bit earlier. I'm very, very excited.
0819 BST: Gordon Farquhar, BBC Radio Five Live
London's presentation is over and my feeling at this point would be that they have acquitted themselves very well. They are attempting to offer something different to the other cities. There was only one question from the floor and an insider who knows about these things has told me the fewer questions the better. Prince Albert of Monaco has asked everyone a question and he did again. It was a technical one about the travel times to the sailing venue in Weymouth and it was answered succinctly. Athletes will have a bed in Weymouth and a bed in the Olympic village.
0725 BST: Gordon Farquhar, BBC Radio Five Live
I was at the IOC party last night. David Beckham was there and the first person to reach over and ask for his autograph were a couple of people from the Paris party.
0716 BST: Andrew Fraser, BBC Sport in Singapore
The final countdown to London's big moment has begun. IOC members are beginning to return from lunch and Lord Coe's team is getting ready to go into the hotel attached to the conference centre. Some key bid figures decided not to watch the three earlier presentations in order to concentrate on their task. England football manager Sven-Goran Eriksson caused a pile-up by the escalators during the break as film crews stopped to shoot him coming up. And Denise Lewis, who looked nervous at London's earlier news conference in Singapore, will speak on behalf of the athletes for London's presentation. They can only hope she shows the steely determination that made her an Olympic champion. To date, however, the most bizarre moment of the day came when the sound of someone whistling Rule Britannia at high volume could be heard coming from a toilet cubicle. A good omen, or maybe just some subliminal advertising?
NEWS FROM AFTER THE PARIS PRESENTATION...
0638 BST: James Pearce, BBC One Breakfast
Most people don't think Paris did much to impress with their presentation. London will soon have their chance to shine. Lord Coe needs to impress with the pressure on. I think he could just pull it off for London if he puts forward their case well enough. I don't want to get people's hopes up but I've been speaking to people in Singapore who think the momentum is really with London. This could go down as a day to remember.
0628 BST: Jonathan Edwards, Britain's former Olympic triple jump champion, speaking to BBC Radio Five Live from Singapore
I wish I was on a beach and someone could text me the result. It's just not a nice feeling - I'm not really enjoying it at all. You have no control, and can do little about it now.
0617 BST: Nigel Adderley, BBC Radio Five Live, Paris
Outside the Town Hall, the big screens are already on showing images of Parisiens enjoying sport in the city. A running track has been laid out in the square but, apart from the media trucks rumbling in, very few people are stopping to get their places to watch the result... yet.
0554 BST: Andrew Fraser, BBC Sport
Moscow gives an upbeat presentation focusing on the difference the Olympics would make for the city, and its delegation leaves the hall to chants of "Moscow, Moscow" from supporters. Proceedings come to an end 13 minutes early as there is just one question from the IOC members about training venues. That gives the VIPs some extra time for lunch before they return at 0730 BST for London's presentation.
0519 BST: Andrew Fraser, BBC Sport
The time in between presentations makes for fascinating viewing as IOC members swap pleasantries, and bid members and journalists try to pull them aside for a quick chat. As New York's team goes off to its news conference, British Sports Minister Richard Caborn is spotted in conversation with Fifa president Sepp Blatter, who will take part in the vote. But Blatter avoids questions from journalists about how he expects it to go, hurrying off back into the hall. French World Cup-winning footballer Laurent Blanc tells me he's happy with the way the Paris presentation went, but resists the temptation to compare it to New York's.
0434 BST: Andrew Fraser, BBC Sport
After an emotive New York presentation rich in humour and focusing on the city's cultural diversity, the floor is opened to questions. That's when things get a bit more uncomfortable for the Big Apple. A Syrian IOC member asks whether athletes from countries on the USA's "terrorism list" would be admitted, and gets told off by IOC chief Jacques Rogge for mentioning a past problem with Atlanta. There is also the inevitable question about New York's hastily revised Olympic stadium plans, and its low levels of public support according to a recent poll. Senator Hillary Clinton described the poll as "misleading" for not "measuring intensity". And in response to Syria's question, bid leader Dan Doctoroff said: "We will allow every single athlete, every coach and every official into our country to enjoy the Olympic Games."
0352 BST: Nigel Adderley, BBC Radio Five Live, Paris
The streets are deserted here on a damp morning in the French capital and the whole city appears to be taking a low-key approach to the decision, in line with the manner of the whole Paris bid, although the television coverage from Singapore has been swooning over the quality of Luc Besson's presentation film. The barriers are out on the Champs Elysee in preparation for a celebration but there's little sign of triumphalism at the moment.
0343 BST: Andrew Fraser, BBC Sport
There are pats on the back as the French delegation leaves the hall, to be mobbed by camera crews outside, while IOC members take a discreet toilet break. Journalists discuss the merits of the presentation, with a few Gallic shrugs and different opinions on the quality of Luc Besson's film. In the Paris news conference, Besson admits he was surprised IOC members clapped, as he thought it was not allowed. "I told my friends not to," he said. Mayor Bertrand Delanoe is asked why no current French Olympians were involved in the presentation, before the briefing wraps up so everyone can watch New York do its stuff.
0309 BST: Andrew Fraser, BBC Sport
The Paris presentation seems to have gone well, with some clever moments, but there are a couple of tricky questions in the Q&A which follows. With Madrid having the highest public approval rating, a Spanish member challenges the city on its claim that the population is 100% behind the bid. And there is an awkward moment when Mayor Bertrand Delanoe gently scolds his bid leader Philippe Baudillon for forgetting to answer one of the questions.
0242 BST: Gordon Farquhar, BBC Five Live
This is definitely a sleek piece of film-making from Luc Besson. The French are trying to reflect ordinary people experiencing the Games in their city. It's a well-made video and pleasant to watch, with the colours of the Olympic rings repeatedly coming back into play throughout it.
0235 BST: Andrew Fraser, BBC Sport
The first montage of Olympic moments appears 17 minutes in, and there is then a mock TV show with French presenter Michel Drucker explaining the Paris media plans. There is also a scene in a cafe which ends with Catherine Deneuve addressing IOC members, along with plenty of classically French mood music. The soundtrack then switches to techno as there are some stirring shots of Paris landmarks at night and French sports fans celebrating.
0200 BST: Andrew Fraser, BBC Sport
Members of the Paris bid team, dressed in grey suits, take centre stage. Mayor Bertrand Delanoe, who is flanked by French President Jacques Chirac, begins his speech to IOC members in French, switches to English, and then back to French. He then introduces a film by director Luc Besson, of Big Blue fame. The film opens with a view of Paris from the air, travelling across the city and finally focusing on the Arc de Triomphe as Olympic rings fly down the Champs Elysees. Sports minister Jean-Francois Lamour then introduces the plans, saying they are athlete-focused, and special effects show new venues springing up out of the ground.
NEWS FROM THE EARLY PART OF THE DAY...
0130 BST: Andrew Fraser, BBC Sport
IOC president Jacques Rogge opens the session with a rundown of how the day will proceed. He tells members they will get a short break between each presentation and for lunch, with a bell summoning them back in each time they are required. Paris will begin their presentation at 0200 BST, with French film director Luc Besson tipped to spring a few surprises. As he enters the hall, Australian IOC member John Coates warns journalists not to assume a city will win if it leads in the early rounds of voting. "It will be up and down all the way through," he says.
0117 BST: Five-time Olympic gold medallist Sir Steve Redgrave telling BBC Radio Five Live about the final London presentation
We will have 30 kids from East London in the room, with the message that the Games are for young people. These people potentially could be competing in 2012.

With just 15 minutes to go to the start of the session, the Raffles City Convention Centre is a hive of activity. IOC members are starting to file in past the security points and journalists are setting up their laptops in the press room. Before going off to shave and put on his suit, Moscow bid director Alexander Chernov tells this website recent voting history favours his city. "The underdog in IOC votes is most likely the favourite," he says. But the Moscow team are not happy about the order of the presentations. With Paris up first at 9am, French President Jacques Chirac can take part before flying to Scotland for the G8. Vladimir Putin will, however, make history when he becomes the first Russian leader to address IOC members in English in a taped message during the Moscow presentation.

In the first round of voting, the 99 voters will have made up their minds and probably decided which city to follow up until elimination. What cities have been working on is the voters' third or fourth preferences, which no-one has been able to fully identify. These final presentations are more critical than ever before. We are told to expect something out of ordinary from Paris, although all the bid teams are being very cagey.
0048 BST: World outdoor triple jump record holder Jonathan Edwards speaking to BBC News 24 about the London bid
I think it's got the potential to do a massive amount for our country. To be host city would do wonders for the self-confidence of our country. The bid has given a boost to our belief in our ability to host the greatest show on earth. The British public is notoriously slow at getting on board. There's a healthy suspicion that they have but in the last six months people have really got behind it.

I think they're going to win, I'm sure they're going to win.

At 7.30am local time the tension is building ahead of the vote to choose the host city for 2012 as members of the London bid team finish their breakfast. The headlines on the local newspaper The Straits Times read: "Wooings over, now it's decision time". The feeling from the London camp is that the wooing has gone extremely well, with Prime Minister Tony Blair lobbying IOC members very hard right up until he flew home to host the G8 summit, and apparently making a big impression. All of London's top bid figures were at a party which followed last night's opening ceremony and had the chance to chat with a host of IOC members. BBC Five Live's Gordon Farquhar, who managed to make it into the party, said: "I spoke to two highly placed IOC figures and they were making positive noises, both about the strength of London's bid and its chances today."
