Nigel Farage - United Kingdom Independence Party
The populist. Usually appearing in newspaper interviews with a pint of bitter beer and cigarette, presumably water will have to suffice on ITV's stage. Farage, the anti-EU campaigner, fresh from his tour of the country in a purple Jaguar in UKIP colors, may seek to portray himself as a lone straight-talker in a sea of politicians. He'll be standing next to Labour's Miliband, which could entertain.
