David Cameron plans to stay in Parliament if he loses 2015 general election

David Cameron has revealed that he wants to stay in the House of Commons even if he loses the forthcoming general election. The prime minister, who has been MP for Witney since 2001, said he loves politics and serving his constituents.

"I have 50 days to fight a vital election, I want to win re-election. It's the country's choice," the Tory leader said.

"If they hoof me out and go for the other guy I'll have to think of something else, but I hope I'll still be an MP. I love serving my constituents, I love politics, I love public service, it's what I care about.

"It's a vocation for me. In the unhappy event I'm not prime minister on 8 May, the people of West Oxfordshire, I hope, will stick with me and I'll stick with them."

The move would mirror Gordon Brown's decision to stay on as MP for Kirkcaldy and Cowdenbeath after he lost the 2010 General Election.

Cameron also told BuzzFeed UK that his party have not planned for the event of a hung Parliament, despite the Tories and Labour running neck-and-neck in the polls.

"I've run a coalition government for the last five years, I think it's been a good and effective government. We've sorted out some of the most fundamental problems this country faces," the prime minister said.

"People know that I will take the steps in the national interest. But I think I am entitled as the leader of a political party to spend the next 50 days fighting for a majority government. I'm only 23 seats short of a majority government."

A digital debate?

The Tory leader also stoked the fires when it came to the issue of the TV leaders debates. Cameron disclosed that he would be keen to take part in a multi-party digital debate following his refusal to go head-to-head with Labour leader Ed Miliband.

"I'm up for a debate, I'm up for a multi-party debate, whether it is you, 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 said.

"Everyone's got to agree to it but I've said very clearly – multi-party debate before the campaign, where do I sign?"

The Liberal Democrats said they would also be interested in a digital debate but argued that it was "no substitute" for the TV format seen in 2010.

"The public deserves to hear the prime minister defend his record in government and his future Conservative offer which involves massive cuts to public services," a Liberal Democrat spokesperson said.

"As a party committed to the idea of giving the public an honest and frank televised debate on the issues which matter to the British people, we will not allow Cameron to dictate the terms of this important issue.

"Nick Clegg will, of course, be happy to debate with Cameron or any other political leader in any format but his continual 'Downtown Abbey' attitude to these debates is simply robbing the public of their rights' to a sensible airing of the issues which matter most to the British people."

The comments come with 50 days to go before the general election, with the Tories two points ahead of Labour (31% vs 29%) in the latest poll from Tory peer Lord Ashcroft.

The survey, which questioned more than 1,000 voters between 13 and 15 March, put Ukip on 15%, with the Liberal Democrats and the Greens on 8%.
