Rebel Labour MPs are certain Sir Keir Starmer's reign is "coming to an end" as the Prime Minister pins his hopes on the state visit of Donald Trump.
Mr Starmer's allies are trying to fend off challenges to his leadership from Andy Burnham as Sir Keir comes under mounting pressure.
Revealed by The Telegraph, the Mayor of Greater Manchester has been laying the groundwork for a leadership bid, with a new campaign group calling on Downing Street to roll out wealth taxes, nationalise utility companies, and end the two-child benefit cap.
Mr Burnham is expected to criticise the Prime Minister at Labour's annual party conference as he calls for a "reset" to help Labour win the next election.
In what has been inferred as a bid to secure an ally at the top of Labour, the Manchester Mayor has voiced his support for Lucy Powell in the party's deputy leadership race.
Senior Labour MP and former leader of Manchester City Council, Graham Stringer, said Sir Keir is "vulnerable" and "supping in the last-chance saloon" following the Lord Mandelson scandal.
Business Secretary Peter Kyle argued in favour of Mr Burnham remaining in Manchester.
Mr Kyle said: "Andy's a real talent. I think he's doing an incredible job in Manchester. I think Manchester really needs him. I like working with him in Manchester. It would be a shame for Manchester to lose him."
Mr Burnham would have to seek a seat through a by-election in order to stand as leader, with one option being the Manchester seat of Gorton and Denton where the MP Andrew Gwynne has been suspended since February after sending sexist messages on a WhatsApp chat.
Polish MEP Dominik Tarczynski calls out Sir Keir Starmer and Sadiq Khan for staying silent on violence at other protests, but reacting to arrests at 'Unite the Kingdom'
Polish MEP Dominik Tarczynski has called out Sir Keir Starmer and Sadiq Khan for staying silent on violence at other protests, but reacting to arrests at the "Unite the Kingdom" march.
Writing on social media, Sir Keir said: "People have a right to peacefully protest. It's our core of our country's values, but we will not stand for assaults on police officers doing their job, or for people feeling intimidated on our streets because of the colour of their skin or background.
"Britain is a nation proudly built on tolerance, diversity and respect. Our flag represents our diverse country and we will never surrender it to those that use it as a symbol of violence, fear and division."
Discussing the statement on GB News, Mr Tarczynski fumed: "At Notting Hill Carnival there were 528 arrests, weapons, 46, sexual offences 18.
"And now at Unite the Kingdom, arrests, 25, weapons zero, sexual offences zero. I didn't see Prime Minister condemning these kind of actions, why?"

Alex Burghart calls for 'someone to take responsibility' with Peter Mandelson's appointment as UK-US ambassador
Alex Burghart, the Shadow Chancellor to the Duchy of Lancaster, has called for "someone to take responsibility" for Peter Mandelson's appointment as UK-US ambassador.
Responding to whether the Mr Mandelson, Jeffrey Epstein saga could overshadow the state visit of Donald Trump, Mr Burghart told GB News: "Absolutely, we were calling on the Government to just come clean about what has happened with the whole Mandelson affair so that it didn't overshadow this visit - this very important visit from the President of the United States.
"They haven't done that, and it has dragged into the start of this week, and we are going to be trying again today to get the Government to publish all of the Mandelson-Epstein files so that everybody can see what the Prime Minister knew, when he knew it, and how this appointment came to be made in the first place."
Should Sir Keir Starmer not come clean about the Mandelson-Epstein saga, Mr Burghart called for questions to be asked.

The Liberal Democrats are calling for an independent inquiry into what was known about ex-US Ambassador Peter Mandelson's friendship with paedophile Jeffrey Epstein at the time of his appointment, saying that victims must be "put first".
MP for Richmond Park Sarah Olney, the party's Cabinet Office spokeswoman, said an independent investigation is needed to uncover what was known, when and by whom, regarding Mr Mandelson's relationship to Epstein.
The Liberal Democrats are also calling for relevant text messages, WhatsApps, and emails to be handed to the inquiry for proper independent scrutiny of how the appointment was made.
Labour MP says Sir Keir Starmer will be 'gone next May'
Labour MP Richard Burgon said Sir Keir Starmer will be "gone next May" unless he "changes course immediately.
Mr Burgon told BBC Radio 4's Today Programme: "Lots of MPs are looking to the elections next May. Unfortunately, the opinion polls suggest they're going to be a complete disaster.
"I think it's inevitable that if May's elections go as people predict, and the opinion polls predict, then I think Starmer will be gone at that time.
"It feels like we are years and years into an unpopular Government, rather than a year into a Government that's just got rid of the Conservatives. We're losing votes to the left, we're going to be losing seats to the right.
"We face a real threat for the first time in our country's history of what I would consider to be a far-right extremist Government - it's the Prime Minister's duty to stop that happening. You can only do that by delivering for people who want real change, and if you can't do that, then of course, there's going to have to be change at the very top."
Mr Burgon continued: "The Prime Minister needs to change course immediately, otherwise, I'm pretty certain he'll be gone next May as it stands."
First Channel migrants to be deported under Sir Keir Starmer's 'one in, one out' deal
The first Channel migrants under Sir Keir Starmer's 'one in, one out' deal are set to leave
| PAThe first Channel migrants are set to be deported on flights under Sir Keir Starmer's "one in, one out" deal with France.
GB News understands that deportation flights will leave this week, but there are no confirmed reports that the first flight will leave today.
Asylum seekers who arrived in the UK on small boats last month have been issued with formal removal directions, telling them that they will be deported back to France within five days.
Some 100 were detained on arrival in the first two weeks of August before their names and details were passed to the French Government for approval.
Confirming the flights are taking off from next week, a Home Office spokesman said: "Under the new UK-France Treaty, people crossing in small boats can now be detained and removed to France.
"We expect the first returns to take place imminently. Protecting the UK border is our top priority. We will do whatever it takes to restore order to secure our borders."
