With one day to go, here is what is happening on the campaign trail:
Gordon Brown will visit 13 constituencies on the eve of the election, covering London, north Wales, the north-west and Yorkshire, before heading up to his home seat of Kirkcaldy and Cowdenbeath, where he will remain on polling day.
David Cameron will continue his 24-hour campaign tour of the UK, meeting people working night shifts and early mornings, such as bakers and florists. Earlier today he was at Darwen (12.45am), Wakefield (3.15am) and Grimsby (5.30am), and will later visit Calverton (9.15am), Dudley (11.45am) and Montgomeryshire (2.30pm), before finally addressing a campaign rally in Bristol (6pm).
Happy birthday, Nick Clegg -- who was elected to parliament this day five years ago. He continues his series of early-morning press conferences at the Work Foundation in London (7.30am). He will then attend a public rally at Western Lawns on King Edward's Parade in Eastbourne with the local Lib Dem candidate, Stephen Lloyd (11am), before heading north to attend a Q&A with students at the University of Durham (Pemberton Building, Palace Green, 4pm). He will round off the day with an election rally at Barker's Pool in Sheffield (6.45pm).
The Scottish National Party leader and First Minister, Alex Salmond, will rally the troops at SNP headquarters in Edinburgh (10am). The SNP is hoping to win 20 seats in the House of Commons this year.
BBC2's The Daily Politics: 2010 Election Debates  will feature the deputy Labour Party leader and House of Commons leader, Harriet Harman, the Conservative shadow Commons leader, George Young, the Liberal Democrat equality spokeswoman, Lynne Featherstone, and the Plaid Cymru MP Adam Price in "The Trust in Politics Debate" (2.15pm). Andrew Neil and Jo Coburn will be asking the questions.
Away from the campaign
Nominations for the five-year post of professor of poetry at Oxford University (annual salary: £6,901) close today. It's an election battle that surely makes the other pale into insignificance. Last year the process was disrupted when one of the nominees, Derek Walcott, pulled out over allegations of sexual harassment, followed by Ruth Padel, who admitted she had told the press about the allegations. Some of those hoping to make it this time are Geoffrey Hill, Paula Claire, Sean Haldane and Roger Lewis.
