LONDON (Reuters) - Prime Minister David Cameron will face off against six political rivals later on Thursday in the first TV debate of Britain's national election campaign, hoping the format will allow him to cast himself as a statesman against squabbling pretenders.
The contest comes before an unusually close election on May 7 in which neither Mr Cameron's Conservatives nor Mr Ed Miliband's Labour Party have a clear lead, leaving the stewardship of Britain's US$2.8 trillion (S$3.8 trillion) economy in the balance.
The debate, due to be held in a former pie factory near the northern city of Manchester, puts leaders of fringe parties like the anti-EU United Kingdom Independence Party (UKIP) and the left-wing Green Party on an equal footing with the Conservatives and Labour, who have dominated British politics for decades.
Leaders of nationalist parties from Scotland and Wales and Mr Nick Clegg, the leader of the Liberal Democrats, the junior party in the country's coalition, complete the lineup.
Mr Cameron, whose personal ratings are higher than those of his rivals, carries bitter memories of the first televised election debates in 2010. Over the course of three such debates, strong performances by Mr Clegg helped deprive the Conservatives of an outright victory. "There's a reason why Cameron was very opposed to having these debates, partly because he thought it distorted the campaign last time, but also because he's the man with everything to lose," said Mr Laurence Janta-Lipinski, associate director at polling firm YouGov.
Mr Cameron successfully resisted pressure to take part in a head-to-head debate with Labour leader Miliband, not wanting to hand his main rival a chance to improve his low personal ratings.
Nor will he take part in a second TV debate next week between the five parties outside the coalition government.
But he and Mr Miliband were last week subjected to separate but back-to-back question and answer sessions on TV. A snap opinion poll afterwards suggested Mr Cameron had come off better, but later polls showed Mr Miliband had exceeded expectations.
The format for Thursday's debate, which will give each leader just 60 seconds to respond to a question, as well as the chance to make opening and closing remarks, is likely to make for a disjointed dialogue, limiting the potential for Mr Cameron's rivals to hold him to account.
"The party that can get out the pithiest quotes, the best one liners, and gets their point across in the most succinct way stands the most to gain from the format we've got," Mr Janta-Lipinski said.
