Andy Burnham's appeal to supporters of Jeremy Corbyn
Andy Burnham will reach out to supporters of Jeremy Corbyn in an appeal for party unity after warning that the Labour leadership race could trigger a "civil war".
The shadow health secretary will say it would be "unforgivable" if infighting after the September 12 result prevented Labour standing up to the Tories.
In a speech at Manchester's People's History Museum, Mr Burnham will say that there are "two visions" for the party and that only he can unite them.
He will add: "Jeremy has brought energy to this race. I want to capture that and involve Jeremy and his team in rebuilding our party from the bottom up.
"I want to show how I can take the best ideas of the other candidates, where there is common ground, and use them to shape my radical vision. In that way, we will come out of this contest as a strong and united team ready to take the fight to the Tories."
It comes after Mr Burnham claimed in a newspaper that a victory for one of his rivals would "plunge the party into civil war because you would have Labour colleagues in different lobbies, bad feeling, disunity, bad blood".
