Where do I sign?published at 20:52 Greenwich Mean Time 16 March 2015
20:52 GMT 16 March 2015David Cameron also discussed the TV debates - and online alternatives - in his BuzzFeed interview. The prime minister said: "I'm up for a debate, I'm up for a multi-party debate, whether it is you [BuzzFeed], whether it is another digital debate, whether it is the TV broadcasters, that matters less to me than having a multi-party debate before the campaign gets under way."
He added: "Everyone's got to agree to it but I've said very clearly - multi-party debate before the campaign, where do I sign?"

David Cameron's kitchenspublished at 20:30 Greenwich Mean Time 16 March 2015
20:30 GMT 16 March 2015During an interview with BuzzFeed earlier, David Cameron admitted that he had two kitchens, just like Labour leader Ed Miliband. The prime minister told the website he had a second kitchen installed in his house in Notting Hill for the benefit of the carers who looked after his disabled son Ivan, who died in 2009.
Mr Cameron said: "We actually had to extend into the basement and we put in an extra kitchen, not least because I had a very disabled son, Ivan, and his carers were there and they looked after him and so we did that for them, as well as for him."
He added: "The point is not whether you have got two kitchens, but whether you have a photocall in one of them and pretend it's your kitchen. That's the issue."

North Sea leader on Budgetpublished at 20:09 Greenwich Mean Time 16 March 2015
20:09 GMT 16 March 2015A lot is likely to be said about Wednesday's Budget over the next 48 hours. And tonight, on the BBC, one leading figure from the oil and gas industry has said the budget could be the most important in the history of the industry in the North Sea. Sir Ian Wood, who was commissioned by the government to undertake a review of the whole sector, called for Chancellor George Osborne to take "really significant" action. Mr Osborne is widely expected to announce a change in the North Sea tax regime. More here.
Labour and SNPpublished at 19:59 Greenwich Mean Time 16 March 2015
19:59 GMT 16 March 2015A bit more on that key story about Labour ruling out a formal coalition with the Scottish National Party. The Labour leader Ed Miliband said there would be no SNP ministers in his Cabinet. Commentators say the two parties could still come to a different arrangement short of a coalition, such as a "vote by vote" deal.
Tonight, in an interview with Buzzfeed, David Cameron said: "Not ruling out a deal, or a pact, or support from the Scottish National Party means that the Labour Party is effectively saying, we're trying to ride to power on the back of a party that wants to break up our country. Now I don't think that is acceptable. The SNP isn't just any old party, they're a party that thinks that the United Kingdom - our country - shouldn't exist. And so I think it is pretty despicable, frankly, not to say 'look there's no dealing with them we're going to do'. And he's not saying that."
