Jeremy Corbyn: Britain's prime minister in waiting?
He never expected to be Labour leader - now he could be Britain's next PM.
Jeremy Corbyn was never supposed to lead the Labour party.
A veteran back-bencher, Corbyn was a rank outsider when Ed Miliband resigned following the May 2015 election. Three months later he beat rival Andy Burnham with almost 60% of the vote after a grassroots campaign amongst the rank-and-file Labour membership.
