David Cameron will not be taking in tonight's debate, a move which his former speechwriter, Ian Birrell, thinks is wise, as the prime minister "hasn't got much to gain".
Ed Miliband, he says, has to hope that he can "talk human" and come across as "vaguely prime ministerial", adding that he felt he was a bit "over coached" in the last debate.

Quote MessageDavid Cameron got warm reaction from crowd in Leeds - 'brilliant', 'persuasive' 'really good'
Image source, TwitterA monthly opinion poll from Ipsos Mori for the Evening Standard, external has given Labour a two point lead over the Conservative party.
These are the numbers:
Labour 35% (+2%)
Conservatives, 33% (unchanged)
UKIP 10% (-3%)
Green 8% (+2%)
Lib Dems 7% (-1%)
David Cameron tells O2 workers in Leeds that voting really does make a difference and there is "a choice" at this election.
Quote MessageI'm not standing here saying I've been the perfect prime minister; I've got everything right. But I'm saying we've got a plan. And the plan is creating jobs, the plan is actually reducing people's taxes, it's building homes, it's building a stronger country. You can stick with that plan and you know what you're going to get...What we did in the last five years which I think has led to this stronger economic situation, the other parties did not support. So I think there is a choice."

Why have the majority of questioners got Tory identity tags on? Another choreographed question and answer farce. It's little wonder he's running scared of genuine scrutiny by voters.

In The Times today, Caitlin Moran says, external some of her friends have "recently started perving on Ed Miliband" - but it seems the Labour leader isn't the only one winning some female admirers.
At Nick Clegg's Blukip press conference earlier, one audience member told the Lib Dem leader that he looked "better looking in real life". You can see how Mr Clegg reacted here, external , thanks to BBC producer Sean Clare.
Some read the horoscopes, or look into a mystic ball, but there is one more way of predicting the election results - with a series of miniature pigs who have silly names.

Image source, TwitterThe Lib Dems have tweeted an image to showing Nigel Farage entering Number 10 as part of a "Blukip" coalition.
Unless we're very much mistaken, it's a doctored image of Nick Clegg entering Number 10 with David Cameron as part of the coalition formed in 2010 - with Nigel Farage's head replacing the Lib Dem leader's.
David Cameron is answering questions from an audience of O2 workers in Arlington Business Park in Leeds. Mr Cameron, who is not taking part in tonight's TV debate, said he wanted to have a debate of his own.

Looking ahead to tonight's debate LSE director Tony Travers says there has been no game changing moment in the election campaign to date, which makes events like tonight even more important.
The "threat and opportunity" is greatest for Ed Miliband, he says, as the Labour leader is the only one on the stage who could form a government.
He's also the only representative of "all old politics", so it's a big challenge, he adds.
