There are now two new post-election party leaders in Britain after Jeremy Corbyn's anointment by Labour as the successor to Ed Miliband. Tim Farron had already replaced Nick Clegg as leader of the much-diminished Liberal Democrats in parliament. Both men are promising a new start of their parties, breaking away with the past.

For new Labour leader Corbyn, this means ditching once and for all the centrist politics of Blairism and opposing the Conservative party much further from the left. For Farron, it is learning the lessons of government after five years of coalition with the Conservatives as the Lib Dems rebuild the support they lost.

The other leaders of the big parties stand firm after the 2015 election. David Cameron of the Conservatives; Nigel Farage of Ukip; Nicola Sturgeon of the SNP; and Natalie Bennett of the Greens. But who do you prefer of these leaders? Vote in our poll.
