Labour leadership rivals Andy Burnham and Liz Kendall clashed over whether the party should have rules to boot out the new leader if they looked like they would fail to win the 2020 election.

Mr Burnham dodged the question - insisting rules already existed for Labour MPs to replace the leader - but finally said: "The party comes first - always", prompting Ms Kendall to interject and say: "Well, the country comes first."

Alistair Campbell, Tony Blair's former spin doctor, vowed to oust the new leader if they failed to make an impact within three years and the idea of keeping the new leader on a type of probation has been backed by senior figures in the party, including shadow education secretary Tristram Hunt. It is a move supported by Ms Kendall too.

Yvette Cooper side-stepped the question over whether she would be happy to be replaced if she fell short, saying: “I’m putting myself forward because it is a tough job and I think it would be a good thing to shake up the old boys’ club in Westminster.”

She attacked Ms Kendall's lack of experience while saying it would be "fantastic" for Labour to elect its first female leader. Ms Kendall shot back, pitching herself as the candidate the Tories most feared, insisting she did not carry the "baggage of the past," adding: “We have to move on from the politics of the comfort zone.”
