Liz Truss is teetering on the brink of annihilation after sacking Kwasi Kwarteng and ripping up key parts of her economic agenda in a bid to save her premiership.
Despite being in No10 for just over five weeks, Tory MPs have been privately discussing how to remove her as Prime Minister - making her the shortest-serving in history.
Speculation has been swirling around Westminster as her new chancellor, Jeremy Hunt, abandoned tax-cutting measures, leaving Ms Truss's pledges in tatters.
In the last 24 hours some backbenchers have also begun to publicly call for the Prime Minister's resignation, including submitting letters of no confidence.
Under the current rules of the 1922 Committee of backbench Tory MPs, a new leader is safe from a leadership challenge for 12 months.
But some are already discussing changing the rules in a bid to remove Ms Truss from office.
Here The Mirror looks at all the MPs who have publicly called for her to resign.
1. Crispin Blunt: The first Tory MP to break ranks told the Prime Minister the "game is up", warning: "It's now a question as to how the succession is managed". On Channel 4 ’s Andrew Neil Show, he said if enough Tory MPs turned against her, the PM would go. He said “Exactly how it is done, exactly under what mechanism... but it will happen.” Mr Blunt, who backed Jeremy Hunt in the leadership contest, released a statement in which he said most of his colleagues "clearly understand that Prime Minister Truss's authority is now fatally damaged". "She has to go now as she cannot win nor sustain the confidence of her colleagues, far less the public and a relentless media."
2. Andrew Bridgen: The MP who has called for every recent PM to go was the second to call on Ms Truss to quit. He told The Telegraph: “We cannot go on like this. Our country, its people and our party deserve better.”
3. Jamie Wallis: MP revealed on Sunday evening he had written to the Prime Minister asking her to stand down as Tory leader and Prime Minister, posting: “The government has undermined Britain’s economic credibility & fractured our Party irreparably. Enough is enough.” Mr Wallis, who came out as trans earlier this year, told the Prime Minister: "Watching senior colleagues exploit the issue of transgender rights and weaponise it in order to score cheap political points was extremely unpleasant. You chose not to challenge this behaviour and have now chosen to have those same colleagues sit alongside you in your government."
4. Angela Richardson: Just after Ms Truss's economic plans were ripped up, the Tory MP told Times Radio it was "no longer tenable" for Ms Truss to remain as Prime Minister. She added: "We saw those unfunded tax cuts. Had that not happened, the markets would not have responded in the way that they did, we would not be seeing the fact that there's potentially an extra 10 billion pounds that we've got to try and plug. And I believe that's 100% down to the Prime Minister, I'm afraid."
5. Sir Charles Walker: The senior backbencher said Ms Truss had only a "week or two" before she'd be forced out. He told Sky News' Beth Rigby: "I think her position is untenable. She has put colleagues, the country, through a huge amount of unnecessary pain and upset and worry. We don't need a disruptor in No 10. We need a uniter." The situation "can only be remedied" with "a new prime minister," he said. Sir Charles gave Ms Truss another "week or two" before she steps down or is forced to resign but later said she should be gone by the end of Thursday 20 October.
6. WIlliam Wragg: The backbench MP told the Commons he had “lodged” a letter of no confidence in Ms Truss to the chairman of the 1922 committee of backbench MPs. He said: “I cannot go and face my constituents, look them in the eye and say they should support my great party. And the polls seem to bear that out.” Mr Wragg said he was "personally ashamed" by what occurred after the mini-budget and stressed: "The lack of foresight by senior members of the Government, I cannot easily forgive."
7. Gary Streeter: Backbencher tweeted: "Sadly, it seems we must change leader BUT even if the angel Gabriel now takes over, the Parliamentary Party has to urgently rediscover discipline, mutual respect and teamwork if we are to (i) govern the UK well and (ii) avoid slaughter at the next election."
8. Steve Double: Agreed with BBC Radio Cornwall that it was a shambles and a disgrace, adding: "Clearly she's just lost control of the government and I think now she does need to do the right thing, step aside and let someone else take over." He added: "For the good of the country, for the good of our party, the game is up. She's been given the opportunity and things are getting worse, not better. The government's paralysed, it can't do anything, it hasn't got the confidence of a very large part - I suspect the majority - of the parliamentary party. And I'm afraid that starts at the top - she just hasn't got what it takes to be Prime Minister."
9. Sheryll Murray: Tweeted: "I had high hopes for Liz Truss but after what happened last night her position has become untenable and I have submitted a letter to Sir Graham Brady."
10. Henry Smith: Told Times Radio the party "can't delay" in finding a new leader. He said: "I think we need new leadership....In a time of uncertainty, we need solid leadership and I'm afraid I'm very sorry to say that has been distinctly lacking from Downing Street in the last several weeks. I think she should do the honourable thing and say that her premiership has made the wrong calls not just once or twice, but consistently since coming into office almost two months ago. And that now it's time for strong leadership to come back to this country, the sort of strong leadership we did actually see under Boris Johnson's administration."
11. Miriam Cates: Told Times Radio "it seems untenable...and yes, I do think it's time for the Prime Minister to go", adding: "The polls are really poor. If there was an election today, clearly, we would be decimated...Our priority right now has to be to govern in the national interest, not thinking about an election, whether that's now or in two years, but to take control of this very, very difficult economic and social situation. And govern for the people. And I think we need a unity candidate."
12. Matthew Offord: The Hendon Conservative MP Mr Offord said Liz Truss needed to agree on a "dignified exit" from No 10. He told the Evening Standard: "I can't see the situation being sustainable. "She does need to sit down and discuss it with her Cabinet and with others to manage some kind of dignified exit."
And a peer - Lord Frost: "The Government is implementing neither the programme Liz Truss originally advocated nor the 2019 manifesto. It is going in a completely different direction," the Conservative peer, who backed Ms Truss to be Prime Minister, wrote in The Telegraph. "There is no shred of a mandate for this. It's only happening because the Truss Government messed things up more badly than anyone could have imagined... Something has to give."
