The planning for peace comes as Mr Corbyn and his leadership rival Owen Smith enter their final days of campaigning.

The results of the contest will be announced on Saturday September 24 at Labour’s annual conference, just over a year after Mr Corbyn was elected with a shock landslide following Ed Miliband’s resignation.

Polls suggest Mr Corbyn is on course to repeat his success, with Mr Smith, the former work and pensions spokesman, lagging far behind.

Mr Smith warned on Saturday that Labour will "disappear" as a serious party if Mr Corbyn wins again.

He said Labour would never win power under Mr Corbyn, insisting he can still win the leadership despite the popularity of his rival with the party's grassroots.

The Pontypridd MP said he had to stand for the sake of his party’s future. “Labour is on the brink of disappearing as a serious party and that would be a disaster.”

In a frank interview Mr Smith joked that his ability to find a girlfriend - now his wife - in a school dominated by boys suggested he had leadership qualities.
