Labour faces a historic split after the election with as many as 100 of the party's MPs set to walk out and form their own breakaway group in an attempt to force out Jeremy Corbyn, The Telegraph can disclose.

Moderate Labour candidates are already in talks with potential donors about a new “Progressives” group forming in Parliament if Mr Corbyn stays on as leader after a Tory landslide.

One potential scenario is for the MPs to resign the Labour whip and become independents grouped together in the Commons under the Progressives banner.

They could then rejoin the Parliamentary Labour Party once Mr Corbyn had been replaced with a leader they supported.

Dan Jarvis, Yvette Cooper and Sir Keir Starmer could be asked to lead the group, although there is no suggestion they have been approached or been involved in the talks.
