Mr Corbyn is also now just 5/1 to be elected as Labour leader on the betting markets, having been 100/1 when he entered the race, according to Ladbrokes. Mr Burnham remains the 8/11 favourite with Yvette Cooper in second place at 11/4. Matthew Shaddick, of Ladbrokes, said: "The queues of punters wanting to back Corbyn are now longer than those at an Athens ATM machine. The betting is beginning to suggest that he might just pull this off."
