Yvette Cooper: 'I have best chance of beating Jeremy Corbyn'
Voting is now underway in the Labour leadership election.
Ballot papers have started to arrive for the 610,000 supporters eligible to vote.
They will choose between the four candidates - Andy Burnham, Yvette Cooper, Liz Kendall and Jeremy Corbyn.
Ms Cooper says she is confident she can beat left-winger Mr Corbyn, the current favourite, to win the election.
