The leaders of Britain's two main political parties faced off in the first live TV debate of the general election campaign on Tuesday, a month before voters go to the polls and with predictions of a record win for the main opposition Labour party. The run-up to the clash was overshadowed by Nigel Farage, whose return to the political frontline could spell even more bad news for the Tories. Farage, whose once fringe idea of getting Britain out of the European Union eventually became mainstream, is standing as a candidate for his anti-immigration Reform UK party. Earlier Farage readily admitted wanting to exploit any Tory ideological infighting after the election. "I don't want to join the Conservative party, I think the better thing to do would be to take it over," Farage told broadcaster ITV.
