Thirty Labour MPs have called on Sir Keir Starmer to resign as Prime Minister after Labour losses hit 1,400 overnight.
Sir Keir suffered an atrocious 24 hours at the polls after Welsh First Minister Eluned Morgan lost her seat and her party fumbled their 72-year-long grip on the country.
Labour also lost hundreds of councillors across England to Nigel Farage's Reform UK as they watched their grasp on stronghold authorities crumble before their eyes.
Tameside, Blackburn, Gateshead and Sunderland, all in former Labour heartlands, including Angela Rayner's backyard, surrendered control to the insurgent party on Friday.
Late on Thursday, it was revealed Energy Secretary Ed Miliband had privately advised Sir Keir to set out a timetable to bow out of No10 with local elections looming.
On Friday, London Mayor Sir Sadiq Khan admitted the "threat to Labour is existential" without a radical overhaul.
And, now, more than 30 of Sir Keir's juniors have followed suit and called for his head.
Richard Burgon, Graham Stringer and John McDonnell are among those calling for the Prime Minister to step down.
However, more surprising outcries come from former Transport Secretary Louise Haigh.
Simon Opher, the MP for Stroud, vowed Sir Keir could not carry Labour through the next general election – nor could he "stop the far right entering No10".
Meanwhile, rebel Nadia Whittome slammed Labour top chiefs for "doubling down on Reform-lite policies", calling for the return of Labour for working-class communities.
The longest-serving Labour MP has piled pressure on Sir Keir Starmer to step down as well earlier this morning.
Clive Betts, the MP for Sheffield South East since 1992, urged Cabinet ministers to say Sir Keir should move out of No10 "in the not too distant future".
"What people said repeatedly was we might vote Labour, we’ve always voted Labour, we might vote Labour again, but not while Keir is the leader. It was repeated over and over again," the MP told the BBC.

"That’s a real problem going forward. I don’t think rebooting and refreshing is going to make any difference.
"Unfortunately, the public, by and large, has just stopped listening to Keir. They have made their minds up."
And, beyond Sir Keir's MPs, Sir Sadiq said the city's results "speak to a far-reaching disillusionment and fracturing in our politics, which cannot be downplayed, spun or dismissed".
"Without a change in course and an acceleration in delivery, the threat to Labour is existential," he declared.
"We risk a repeat in London, Wales and across England of what happened in Scotland, where we have still not recovered."
Sir Keir has insisted that he would not "walk away" and "plunge the country into chaos" with his resignation.
The beleaguered PM added: "But that doesn’t mean we don’t need to respond. It doesn’t mean we don’t need to rebuild. It doesn’t mean that we don’t need to set out the path ahead.
"That’s what I’m going to do in the coming days."
