Despite this, a senior party insider told The Sunday Times that they are “determined to bring this to a head. The current position is not sustainable”, while a source close to Sir Keir Starmer said that Mr Corbyn’s time in the party was effectively over.

The Telegraph reported last month that Mr Corbyn was considering establishing his own political party after privately accepting that he would not have the whip reinstated.

Party insiders were understood earlier this year to be supportive of Mary Creagh, a former Labour MP for Wakefield who lost her seat in 2019, to stand against Mr Corbyn who presided over the election that cost her place in Parliament.

It comes as Labour continues to be involved in a public spat with the Unite union, one of its closest allies and biggest donors during Mr Corbyn’s tenure as leader.

Sharon Graham, the general secretary of Unite, said this week that it would be reviewing £1 million of its remaining funding, which could leave the party bankrupt.

A Labour spokesman said: “We have publicly set out the process required for Jeremy Corbyn to come back into the Parliamentary Labour Party. The ball is in his court.”
