"It's a big decision and I'm listening to local people. I don't shy away from difficult decisions.

"I'll think about this very carefully, I'll make my decision, and I'll be accountable for it and explain it to local people, just as I always have."

Former shadow cabinet ministers Chuka Umunna and Chris Leslie revealed that they had resigned the whip, alongside Ann Coffey, Angela Smith, Mike Gapes, Luciana Berger and Gavin Shuker to form the new group on Monday.

Ms Ryan's announcement came as Labour launched a consultation on changes to allow voters to force MPs to seek re-election if they swap parties.

Members of the new group have indicated they will resist demands from Labour bigwigs, including John McDonnell, to step down and seek a fresh mandate from voters in a by-election.

Ms Ryan made clear she is hoping for further defections.

In a letter to constituents, she said she hoped her actions would act as a "wake-up call" and "others will join us".

Ms Ryan said that under Mr Corbyn, Labour had developed a "cult around the leader", driven by an " all-consuming narrative founded on rage, betrayal and the hunt for heretics".

On the issue of anti-Semitism, she said: "I have been appalled and angered by the Labour leadership's dereliction of duty in the face of this evil."
And she added: "Jeremy Corbyn has enabled and allowed a toxic culture to develop in too many parts of the Labour Party.

"And I can't be a part of it any longer. Which is why, with a heavy heart, I have left it."

With a poll taken on the day after the Independent Group's launch putting the breakaway MPs on 10 per cent support to Labour's 26 per cent nationally, Mr Corbyn's party would be hopeful of seizing back most if not all of the seats in by-election contests.
