It's been quite a year in British politics.
A year of sudden departures, new arrivals, electrifying performances and high drama.
Tony Blair won an historic third term in government for Labour - and then suffered his first Commons defeat, on the 90 day detention of terror suspects.
The Conservatives crowned their fifth leader in eight years - and took an immediate lead in the opinion polls. And David Blunkett quit the Cabinet for the second time in 12 months.
But when the dust settles on 2005 which single event will remain longest in the memory?
We want your nominations for the defining political moment of 2005.
It doesn't have to be the biggest event, necessarily, but it does have to be the most memorable - something that, for you, captured the essence of British politics in 2005.
Perhaps it was Britain winning the 2012 Olympics bid - or Tony Blair's response to 7 July bombings in London.
Or Reg Keys, who lost his son in Iraq, urging Mr Blair to say sorry for the war at the Sedgefield general election count, while the Labour leader looked on impassively.
What about David Cameron wowing the Tory faithful in Blackpool... or being bear-hugged in the street as he launched his leadership campaign?
How about Lib Dem leader Charles Kennedy and wife Sarah unveiling their new son in the middle of the general election campaign?
Or octogenarian peace campaigner Walter Wolfgang being ejected from Labour's annual conference in Brighton?
Or George Galloway's dramatic appearance before a US Senate Committee?
Perhaps it was none of these and you have your own favourite moment of 2005. Send in your suggestion - and why you have chosen it - using the form below.
We will draw up a shortlist of the most popular moments and hold a vote to find a winner.
We can't promise prizes but we will publish the most entertaining and interesting suggestions on the site.
Here are some of your suggestions for the political moment of 2005:
George Galloway's appearance at the US senate has to be the political moment of the year. It was if the new kid walks into school and takes on the chief bully and wins. He wiped the floor and his oratory was stunning

When the Labour Party and Tony Blair won a third term in government - Brilliant!
Sarah Thomas, Hemel Hempstead, Herts
Mr Wolfgang being ejected from the Labour conference was by far the greatest political moment of 2005. I think this because it shows the censorship currently oppressing our society, especially as an "octogenarian peace campaigner" can be kicked out of a party conference. It also shows how labours hold on the country is starting to crumble, even their own party members are rebelling publicly.

The first defeat of Tony Blair in parliament on November 9th 2005.
This was the day that the steady encroachment of British civil liberties was finally halted and our elected representatives finally started fighting for our freedoms in parliament.

The Jeremy Paxman interview of George Galloway during the election coverage. Truly there's no better man to interview him...
Gav Maclean, Edinburgh, Scotland
Reg Keys' speech really brought Blair back down to our planet - to see his face when Mr Keys basically opened his heart was as priceless as it was poignant.
Daniel Entwisted, Bolton, England
Has to be the brief segment of Ken Clarke's Blackpool speech when he said, "We're searching for a leader who is a Prime Minister in waiting.....Well boy have you kept me waiting!". Typical arrogance and confidence of the man rolled into one, priceless.
Gareth Davies, Anglesey, North Wales
The passing of a political era is rarely noticed at the time, but my "Ceausescu moment" was Cameron's first Prime Minister's Question Time. His famous "You were the future once", and "it's only my first PMQ and you are already asking me the questions", and best of all, his splitting of Blair from his party with "We'll support Education reforms...so that they will get through the Commons, so that you can be at your best, which I'm told is when you're bold". You could hear the grinding of Labour backbench teeth with that one.

For me the Make Poverty History rally in Edinburgh on July 2nd - the biggest ever anti-poverty rally in the UK - was the political moment of the year.
The key mobilisation of a campaign that's been backed by 10 million people in the UK (more than the 9.5m who voted Labour at the last election) there could be no stronger political message!
Nicholas Kafka, London, UK
Surely the occasion when Jeremy Paxman charged John Reid with being Labour's "attack dog" on Newsnight! The good doctor's reaction was side-splittingly funny, especially when he turned on Mr Paxman and accused him of ridiculing his Glaswegian accent, thus completely losing the plot. Another quality Paxman moment.
Colin Hoad, Croydon, England
I think the first speech of David Cameroon and Tony Blair in the House of Commons was particularly poignant because of the way David addressed the nation rather than the members of the House. This speech seemed to be well rehearsed and its delivery was very in tune with the attitude of the general public. There seemed to be an air of authority about David's personality that caught Tony out. Also the fact that Tony did not come back with any original ideas within the following few days showed how much lack of enthusiasm the prime minister has.
Tariq Zaman, Loughborough, Leics., UK
For me the most outstanding and perhaps defining political moment of 2005 was the aftermath of the 7 July bombings, though not so much the reaction of our men of state as of the population at large. In practice who, after all, carries the largest voice to the world if not a nation united in suffering? I felt that Britain's reaction reinforced an image of a nation that keeps its head in a crisis. We were brought face to face with the multiethnic nature of our society in a way which at once highlighted all its pros and cons, and in spite of some inevitable confrontation still managed to ask the right questions and keep what could have been a potentially disastrous situation relatively well under wraps. That, I feel, is something to be proud of. I only hope our questions get the right answers.

The arrest and prosecution of peaceful demonstrators outside No. 10 Downing Street because this signifies the end to our freedom of speech and our democratic right to demonstration. This is the manifestation of a dictatorship.
Elisabeth Griffith, Penarth, UK
The death of Mo Mowlam. The death of a brave, intelligent and engaging woman was a tragedy for British politics. Different to all other politicians in her style and outlook she was instrumental in the Good Friday Agreement and it is a shame that she was shuffled out of the job on NI secretary, that she left the commons and of course that she died so young, with so much potential remaining!
Matt Stephenson, Manchester, UK
Not the most significant moment of the year, but certainly a humorously memorable one... remember Charlie Kennedy making a complete mess of trying to explain Lib Dem tax policy during an election press conference just hours after his wife had given birth? He looked clueless and exhausted!
What a difference a speech makes. Cameron has just won the Tory leadership contest so easily that people forget that David Davis was miles ahead of him before his Conference speech. If he had won, he would have been another Tory grey suit in the mould of Duncan Smith and Hague. Cameron is already setting the political agenda. If Cameron eventually becomes PM, that speech will be seen as historic.
Tom O'Gorman, Dublin, Ireland
The hilarious response to the election of David Cameron as leader of the Tories. The extent of the desperation of those who dislike Blair and Labour was seen in their hysterical grasping at the straw of a completely untried and inexperienced toff who had a couple of reasonable one liners at PMQ. Bluntly Hague was far more impressive in the Commons but look what happened to him!
Phil, Market Drayton
Has to be Dennis Skinners "lines of coke" moment in the commons... classic!
Cormac Kennedy, London
The moment has to be when the media showed the slowed down look on the prime minister's face the exact second that he realises that his career has come to an end and that the Conservatives might just win the next election, delivered with the killer line "you were the future once".
The first (and so far only) government defeat in the Commons, engineered by populist crowd-pleasers, rent-a-gob rabble and misguided civil libertarians. Is this the beginning of the end? And on whose conscience should it be?
Jane Griffiths, London, UK
February 18th, when hunting with dogs was finally consigned to the dustbin of history where it belongs, when the Hunting Act became law.
Chris Gale, Chippenham, UK
I think the Iraqi elections. Whatever anyone's opinion of the rights and wrongs of the war, the sight of people turning out to vote in huge numbers despite the threat of murder and terror should remind us all of the value of the democratic rights about which we are so apathetic at times.
Anthony Jones, Leeds, UK
When the troublesome and rebellious backbench Labour MP Bob Marshall-Andrews thought he had lost his seat he blamed Tony Blair. Later that evening it became clear that he had actually won so Jeremy Paxman asked him if he would give the credit to Tony Blair. Very amusing.
George, Berkshire, UK
Election of David Cameron to leader of the Conservative - a huge step forward for the party and the country!
