Liz Truss is thought to be eyeing up a colossal Budget U-turn over her flagship vow to cut corporation tax.
This evening Chancellor Kwasi Kwarteng said "let's see" when asked if parts of the disastrous mini-Budget were going to be torn up.
Discussions are said to be under way in Downing Street about ditching the £19bn-a-year tax cut after Tory MPs warned it left a black hole in the economy.
The move - called for by multiple Tory MPs - would be the second major U-turn over Liz Truss ’s disastrous mini-Budget after she dropped her 45p rate Income Tax cut for the rich.
Tory anger spiralled last night after Ms Truss claimed she would not cut spending to pay for her plans, leaving a £60bn black hole.
She faced what one MP called a “machine-gun” of questions by backbenchers with one, Rob Halfon, telling she had trashed 10 years of working class Conservatism.
A crestfallen Tory MP told the Mirror that Liz Truss’s “authority is seeping away in front of us” and she could be forced from power. The MP branded the mini-Budget "absolutely catastrophic".
A reversal is looking increasingly likely, with the Chancellor now hinting his plans may change in the coming days.
In an interview with The Telegraph Mr Kwarteng responded "let's see" when quizzed about a change to his corporation tax proposals.
And asked if anything else might change he said: “I’m not going to play those games about what’s in or out or any of that. What I'm totally focused on is making sure that we get growth in the economy.”
While he maintained there would be “no real cuts to public spending”, he admitted that "difficult choices" lay ahead, stating: “Let’s face it, there are difficult choices within that you have to prioritise."
Ex-Chancellor Rishi Sunak had planned to raise corporation tax in April from 19p to 25p for many firms. Liz Truss vowed to cancel that in a major leadership pledge.
A source told The Sun corporation tax would not hit 25p - but it would still rise under a proposed U-turn.
Another source told Bloomberg a decision would be made after Mr Kwarteng returns from IMF and World Bank meetings in Washington.
Mr Kwarteng insisted "our position has not changed", adding: "I will come up with the medium-term fiscal plan on October 31, as I said earlier in the week, and there will be more detail then."
Pressed on reports of a U-turn, he said: "I speak to No10, I speak to the Prime Minister all the time.
"We are totally focused on delivering the growth plan. What we were facing was a tax high of 70 years and no growth."
Asked if a U-turn on cutting corporation tax looms, he said: "My total focus... is on delivering on the mini-budget and making sure that we get growth back into our economy.
"That's the central prize, that's the main focus of my job."
Asked if both he and Prime Minister Liz Truss would still be in office in a month, Mr Kwarteng said: "Absolutely 100%. I am not going anywhere."
It comes after IMF managing director Kristalina Georgieva delivered a rebuke to the British Government, saying: "Don't prolong the pain."
At a press conference in Washington, she said: "Our message to everybody, not just the UK, is that at this time, fiscal policy should not undermine monetary policy."
She said that "if it does, the task of monetary policy becomes only harder", as it can increase "rate-tightening conditions".
"Don't prolong the pain - make sure actions are coherent and consistent," she said.
"It is correct to be led by the evidence, so if the evidence is that there has to be a recalibration, it's right for governments to do so."
Tory former chancellor George Osborne suggested Mr Kwarteng should not wait until his October 31 statement before making the "inevitable" U-turn.
"Given the pain being caused to the real economy by the financial turbulence, it's not clear why it is in anyone's interests to wait 18 more days," he said.
Shadow Chancellor Ed Balls tweeted: "I agree with George."
Tory ex-minister David Davis branded the mini-Budget a "maxi-shambles" and said reversing on some of the tax cuts could see off a leadership challenge.
"If they do that I think people like Mel Stride and others will come in behind them and they buy some time," he told ITV's Peston.
Damian Green, a former deputy PM, said Conservative MPs are openly discussing reversing some of the mini-budget measures, as they question how else she can reduce debt after she rejected public spending reductions.
"It is indeed a topic of conversation around the tea rooms of the House of Commons as well, because we can all do the rough maths and see that it's very difficult," he told BBC Radio 4's PM programme.
"One of the obvious ways would be possibly to defer some of the tax cuts or the failure to put taxes up."
Journalists attending Work and Pensions Secretary Chloe Smith's first big speech were told: “The Secretary of State is not going to want to answer questions on this morning’s announcement about the mini-Budget.”
Ms Smith refused to rule out more U-turns over the mini-Budget. She told journalists: “I’m not in a position to answer your question…. That will be a matter for the Chancellor to announce in due course.”
The proposed U-turn emerged just an hour after Downing Street insisted there would be no more U-turns.
Asked if the Prime Minister promised no more reversals, her official spokesperson said: "Yes, as I said to a number of questions on this yesterday, and the position has not changed from what I set out to you all then."
Downing Street refused several times to deny talks were under way about a possible U-turn on corporation tax.
Asked if discussions were under way a No10 spokeswoman said: “I wouldn’t comment on meetings that the Prime Minister has. She’s working from Downing Street today. There’s ongoing work.”
Asked if it was still the position there would be no U-turn, she said: “Yes, our position hasn’t changed and you heard the Chancellor say that himself just a little while ago.”
But asked repeatedly if the position could be about to change imminently, she refused to rule it out.
A Treasury source said they were unaware of aspects of reports about a possible U-turn.
Shadow Chancellor Rachel Reeves said: “Today’s mess shows the utter chaos this government is in. This is a crisis made in Downing Street and working people are paying the price.
“Labour has said repeatedly that they need to reverse the kamikaze budget and restore confidence.
“This is now urgent as the Bank of England’s intervention in the markets ends tomorrow. The Tories cannot allow the chaos caused by their mini-budget to continue any longer.”
