Here's a summary of the main political stories of the day:

Nick Clegg said no party would win an outright election victory and warned voters they face a choice between the Lib Dems, the SNP and UKIP over who holds the balance of power. Launching his manifesto, external , the Lib Dem leader said he would seek to form a "coalition with conscience" that would not "lurch off to the extremes".

UKIP - which also launched its election manifesto, external today - said it would make working people better off through a "low-tax revolution".

Working grandparents could share unpaid parental leave under plans being launched by the Labour Party as part of its women's manifesto, external .

In an interview with the BBC's Evan Davis David Cameron says accusations that the Conservatives are "the party of the rich" make him "more angry than almost anything else".

Lib Dem David Laws says he has "no confidence" in Labour to balance the budget, equally he says the Tories are set to make "swingeing cuts" which the Lib Dems would not accept.

Schools minister Mr Laws also dismissed claims made in the tabloid press that his party was set to lose all its seats in the south west as "complete and utter rubbish".

In a speech tomorrow, Labour's Ed Balls will urge the Tories to "come clean" over where they would find an extra £25bn a year to fund a series of generous general election manifesto commitments.

Labour says the bill for "panicky promises" - such as raising annual NHS funding by £8bn and £6.5bn to raise the income tax allowance to £12,500 - represents a cost of £1,439 for every working household.

Newsnight is on BBC2 now - and they're showing the best bits from Evan Davis's interview with David Cameron that was broadcast earlier today.

Lib Dem leader Nick Clegg has insisted it is "ludicrous" to question whether a Liberal Democrat candidate filmed at a strip club on his stag night was fit to be an MP.

Leaked CCTV footage showed would-be MP Maajid Nawaz having a private lap dance at an east London strip club last summer.

Mr Nawaz, who is standing in the marginal Hampstead and Kilburn seat, has apologised to the Lib Dems for the "distraction" caused by the footage of his visit to the Charlie's Angels club.

Asked about the incident, Mr Clegg said: "I'm the leader of a political party, not the thought police. He has not broken a law; he has done something which people might not approve of.

"What's next, that someone goes on a hen night and sees the Chippendales and I start disqualifying them?"

If you missed the entertaining political sparring between Queen's Brian May, night club owner Peter Stringfellow and barrister and FA director Heather Rabbatts earlier, here's a treat for you.

In Scotland today the Scottish Tory leader Ruth Davidson visited three textile mills in Hawick in the Borders in an effort to show the party's support for small firms.

Ms Davidson said she was "impressed by the work that's going on" to bring the next generation of workers through "in-house modern apprenticeships". She added: "Businesses know that to thrive, they have to invest in their workforce. The Scottish Conservatives support expansion of the apprenticeship programme to get more young people into industries like textiles, and are keen to support Scottish manufacturers exporting abroad."
