And so concludes our election live text for the night. Looking ahead, Sunday's papers include a plethora of opinion polls. Join us from 0730 for the day's coverage.
Sarah Brown, the wife of the prime minister, says the election campaign so far has not been "about big P politics, as in people shouting at each other in the House of Commons. It's about the policies that make life better or worse", she writes in her diary for the
Conservative leader David Cameron tells the Sunday Telegraph that he will govern on behalf of "everyone in Britain".
A poll in the newspaper
has the Tories' lead rising to eight points, with the party on 38%, Labour on 30% and the Lib Dems on 21%.
The Labour manifesto, which is due to be launched next week, will include "no big new spending commitments", according to party sources - but it will have a promise to double paternity leave from two to four weeks, says BBC political correspondent Gary O'Donoghue.
message to Labour members,
Business Secretary Lord Mandelson says that now is "not a time for a business-as-usual manifesto" ahead of the launch of the party's programme on Monday. He predicts that tax and spending will be the "slow burning fuse under the Tory campaign" as it was in 2001 and 2005.

Graham writes: Yes I support the Conservatives on this issue, and I am amazed at the opposition and backlash to the proposal. In the past generation we have seen an unprecedented decline in the popularity of marriage, alongside a steady increase in family breakdown and disfunctional families.
Icebloo writes: Same old Tories. They haven't changed at all no matter how much they claim. Getting married for financial advantage is absolutely the wrong reason to get married - this kind of thinking belongs in the 1800s with the rest of Tory party policies.
Anon_Mind writes: So if I don't declare my love for my partner to 'God' at the expense of thousands of pounds I won't be eligible for a tax break that will buy me a box of cereal per week. Hardly an incentive, doesn't take into account that there are couples out there who would rather spend their money on things other than a wedding and is an insult to every voters intelligence.
Labour MP Gordon Banks has written to Scotland's first minister Alex Salmond to complain after Gordon Brown was heckled by the SNP's Keith Brown, the Scottish schools minister, during a visit to Ochil, Perthshire.
The polls are now coming thick and fast - a ComRes poll in the Independent on Sunday and the Sunday Mirror has the Tories up two to 39%, Labour also up two to 32%, the Lib Dems down four to 16% and the others unchanged on 13%. No fewer than 63% of those interviewed agreed that neither Labour nor the Conservatives were being honest about public spending, with 27% disagreeing. The polling firm spoke to 1,001 adults on 9 and 10 April.
Shadow chancellor George Osborne has been blogging his thoughts about the first few days of the Tories' campaign, saying his party have "had a strong start" and warning ruefully that "Labour and the Lib Dems have nothing positive to say on the economy".

News of the World
poll of key marginals has Labour on 37%, the Tories on 36% and the Lib Dems on 19% in 96 Labour-held seats where the Conservatives need a swing of between 4% and 10% to win. The ICM survey of 1,001 adults, conducted on 7 and 8 April, shows Labour unchanged, the Tories down four points and the Lib Dems up five since the exercise was last conducted in January.
Last week Labour released a poster with
David Cameron's head superimposed onto the body of Ashes to Ashes' Gene Hunt.
Now, rather cheekily, the Scottish National Party have produced their own version with Scotland's First Minister Alex Salmond posing on the bonnet of Hunt's famous motor, telling Scots voters that the only way to "fire up the Quattro" is by voting SNP for "fair fuel prices".
The BBC's Claire Gibson says: The Labour leader's flight back from Scotland to Stansted was delayed for half an hour on the tarmac at Edinburgh after the plane's computer system needed to be re-booted. On the tannoy during the flight, the pilot said: "This is probably the most high-profile flight I have ever done and right now I'm really embarrassed by the delay, but safety must come first." However, Gordon Brown appeared to win over this one voter by sitting patiently in his seat as the pilot added: "Good luck on 6 May!"

In an interview with the Pink News, David Cameron announces a Conservative government would change the law so historic convictions for consensual gay sex would not need to be disclosed when applying for jobs or on criminal record checks.

The Lib Dem "town hall debate" in Gateshead has wrapped up after some strong questioning from the audience.
The BBC's Raymond Buchanan, just back from reporting on Gordon Brown's walkabout, says the PM chanced upon the wrong man during his visit to Dollar, in the Ochil and south Perthshire constituency. He visited the street where the SNP's Scottish schools minister Keith Brown lives. The former Royal Marine shouted: "Are you going to apologise for Iraq, Gordon?"
Back at the Lib Dem event, the BBC's Fiona Trott says: "Some people tell us they've been asked to come here by the event organisers. Nick Clegg's people say they have used an outside company to get the numbers up but nobody has been vetted and the audience does include non-Lib Dem voters."
Plaid Cymru's Elfyn Llwyd says of the protests about public sector cuts in Glasgow and London: "The London parties cannot ignore the voice of a whole range of workers in the public sector. The savage cuts proposed by all three risk sending us into another recession and [damaging] Wales - which has an economy especially dependent on the public sector - even further."
Nick Clegg has just been put on the spot as to whether he is a "true democrat" and wants to replace the monarchy. He replies that fixing the problems of Parliament is his "top priority", rather than "laying into the Royal Family".
Update on TIEWATCH: After adopting a casual open-necked approach while dabbling in the art of dry-stone walling earlier, Nick Clegg's collar is firmly secured by a bright Lib Dem yellow tie for his appearance in Gateshead.
Summing up the demo against public sector cuts in central London, the BBC's Jane Bennett-Powell says: "The blue sky and the brass band brought a holiday feel to Trafalgar Square but gradually the tourists found themselves sharing the steps and the benches with people fearful of job losses."
Back in north-eastern England, it's Mr Clegg's turn to be interrupted with some Paxman-esque questioning about immigration from the floor. Who says these politicians have an easy life?
While Mr Clegg's meeting in Gateshead seems very civilised, Labour's John Prescott is bellowing into a microphone in Openshaw, Manchester, where he is being taken to task over pensions by an equally vociferous 82-year-old lady.
It's questions from the floor in Gateshead and Mr Clegg is asked about joining a coalition. He says politicians from all parties will have to work together, regardless of the election's outcome, because of the tough economic decisions required.
Mr Clegg derides his rivals for baulking at finalising a deal to reform party funding and blocking other reforms through a "cosy stitch-up".
"Wrong, wrong, wrong" is how Mr Clegg describes bright eight year olds from poor families being overtaken in class by less intelligent youngsters from wealthier families. He promises big changes in education.
The BBC's Claire Gibson, on board Gordon Brown's flight back to London, says they've removed copies of the in-flight magazine, the Spectator, backing David Cameron to be the next PM.
Lib Dem leader Nick Clegg has taken to the floor at his debate in Gateshead. "The 'Newcastle' banner was removed before the public spotted the mistake," reports the BBC's Fiona Trott.
So, we're nearly ready for the off in the Grand National at Aintree but poor jockey Ruby Walsh won't be riding the favourite after breaking his arm. Fingers crossed the party leaders make it safely to the first hurdle of the election campaign with Thursday's TV debate.
Sean Morton tweets: For the first time in the election everyone at work is talking about it. And they're all ripping the Tory married tax plan.

Another update from the BBC's Fiona Trott: "The Lib Dems are busy putting out chairs for Nick Clegg's 'town hall debate'. The banners say 'Newcastle' - we're actually in Gateshead. Bad news for the leader, who's about to say that Labour has let down the North."
In Gateshead, the BBC's Fiona Trott has learned that the theme of Nick Clegg's speech this afternoon will be that Labour "has betrayed people in the north of England".
Senior Labour sources on the campaign trail in Kirkcaldy tell the BBC's Claire Gibson that Gordon Brown is not a betting man. So much for our hunch about the prime minister's Grand National pick then.
Comment from Gordon Brown talking to the BBC's Iain Watson: "It is about substance at the end. The British people are very discerning and at the end of the day will look at who's giving them the answers to the big questions they are asking. It's not personal, it's about substance."
Spectator editor Fraser Nelson tweets his top 10 reasons for voting for Cameron. At No 1? School reform.
Here's his list
A less-than-favourable view of Gordon Brown from across the Atlantic. The New York Times describes him as "a man who can seem dour, distracted and dysfunctional". That is why, it says, Sarah Brown is trailing around the country with him, to function as his "designated humaniser".
Public sector workers have taken part in a protest against potential public sector cuts after the general election. Pensioners, trade unionists, students and other campaigners marched to Trafalgar Square in central London.

More speculation about the leaders' Grand National bets: David Cameron will no doubt be backing The Package to secure victory - and hoping his Conservatives have the right bundle of tax measures to do the same.
Sam from Darwen, UK, writes: While dear leader Brown is busy explaining how the tax break for married couples will make families with kids worse off, he could explain how abolishing the 10p tax band made millions of people worse off.
The chief executive of the Childcare Trust charity joins the debate over tax breaks for married couples, saying families with children face more expense than married couples without. "We would be very concerned if tax breaks for married couples were introduced at the same time as tax credits were reduced," Alison Garnham says.

Gordon Brown says the Tories' marriage tax break proposals will leave families with children worse off. "What this is about is giving a little with one hand and taking away a lot with another," he says. The Tories are planning to cut child tax credits for middle-class families, Sure Start children's centres and Child Trust Funds, he adds.
The Unite union responds to Labour's proposed "Cadbury Law" saying there's a need to introduce a new law to safeguard industries in the national interest. But the union said it does not want to prevent foreign takeovers. Rather it is "keen to prevent short term investors such as hedge funds making a quick buck from a takeover".
David Cameron is now set to do some canvassing in Cheam High Street. Perhaps he will pop into one appropriately-named shop - a hairdressers called "David Cameron".

The Lib Dems have been proposing a public interest test when it comes to takeovers of UK firms for some time, treasury spokesman Vince Cable says, commenting on Labour's proposed "Cadbury Law".

Henry Clarke Price from Oxford writes: Oxford University's Student Union has just emailed all students to tell them to vote in Oxford rather than their home constituencies: "The student vote will be VERY significant in both Oxford constituencies and as a voter in Oxford you will be able to influence the election more than in many other places", SU president Stefan Baskerville wrote in his email.

Talking about marriage, David Cameron tells the Daily Mail his wife is "not flashy". He says: "Sometimes I'll get back from meeting President Sarkozy, or someone, and Sam will say 'Yeah yeah, that's all very well, but it's your turn to cook dinner and put the kids to bed'.''
But Schools Secretary Ed Balls says the money would not go to those who really need it. He says the Tories are saying "if you don't fit a certain type of family - a one earner family - then you're second class".

Good morning, and welcome to our coverage of day five of the general election campaign. It looks like people will have plenty to say about the Tories' plans to give four million married couples tax breaks.
Could the tide be turning in the National Insurance row? Several newspapers lead with attacks on the businessmen who have backed the Conservative stance. Perhaps the Tories hope their married couple's tax break will move the debate on over the weekend before any sort of potential backlash can gather steam. The tax break is certainly going to be a big talking point in the coming days - as is Labour's Cadbury's Law. Sounds tasty
will voters agree?
Newsnight's political editor Michael Crick says Cadbury's Law will be a hard policy for the Conservatives to criticise. It's a patriotic issue - protecting UK firms from predatory foreign companies - and is likely to appeal to many traditional Tory voters, he says.
"Cadbury's Law" is set to be a feature of the Labour manifesto, BBC Newsnight has learned. The policy has been prompted by the Kraft takeover of British chocolate giant Cadbury - American firm Kraft promised to keep the main factory open before the deal was agreed, but then changed its mind afterwards. Under Cadbury's Law, it would be harder for overseas takeovers of UK companies to happen - requiring two thirds of shareholders to agree, not 50% as it is now. Newsnight's economic editor Paul Mason says it's the main concession to the Unite union in the Labour manifesto.
"Migrant city's cry for help," is the Daily Mail's front page. The city in question is Peterborough, the plea comes from two independent councillors to the main party leaders. It lays bare "the devastating impact of uncontrolled, mass immigration on the fabric of English life", the paper claims.
The Daily Telegraph leads with the Tories' tax break for married couples and civil partners. The Financial Times takes a different view of the same story, focusing on the £1billion levy that would be slapped on UK banks in order to pay for it. The paper is sure that, unsurprisingly, the move will cause great anger in the City, especially if the Tories go ahead with it without a commitment to a similar levy from other competitor countries.
A second paper apparently unhappy at those Tory-supporting captains of industry is the Independent - its front page on Saturday reads, "Mind your own business!"
The first editions of Saturday's newspapers are starting to arrive. The Guardian's slightly startling headline is, "Cable attacks 'nauseating' businessmen". Lib Dem Treasury spokesman Vince Cable has told the paper he finds it "utterly nauseating all these chairmen and chief executives of FTSE companies being paid 100 times the pay of their average employees lecturing us on how we should run the country".
"Patronising drivel that belongs in the Edwardian age" - that's the Liberal Democrat verdict on the Tories' marriage tax break. "David Cameron clearly has no idea about modern life," they say, and is trying to create "rigid rules or special policies that help some families but not others".
A bit more on the married couples' tax break. We understand it would work by allowing people who are married or in a civil partnership to transfer part of their tax free personal allowance to their spouse or partner. It would apply only to basic rate taxpayers earning less than £44,000 where one couple doesn't use their full personal allowance.
Four million married couples and civil partners on low and middle incomes would get an annual £150 tax break under Conservative plans to support marriage in the tax system, the BBC's James Landale reports. It would cost in the region of £550million a year and would be funded by the Tories' planned banking levy. They say they hope to introduce it next year in the Budget of 2011.
