The chancellor has insisted he is "not going anywhere" amid the economic turmoil - and when asked if he was about to do a U-turn on corporation tax he said: "Let's see".

Speaking earlier in the US where he is attending IMF meetings, Kwasi Kwarteng told reporters that he remains "totally focused" on delivering the government's growth plan.

Later, in response to a question about how markets "have improved today because they think you're about to do a U-turn on corporation tax", Mr Kwarteng said: "Let's see," according to The Telegraph.

It is his strongest indication yet of a possible change of course.

During a visit to Washington, Mr Kwarteng was asked whether he and Liz Truss, the prime minister, will be in their jobs this time next month.

"Absolutely. 100%. I'm not going anywhere," he said.

The chancellor admitted there has been some "domestic turbulence" since he unveiled his tax-cutting mini-budget at the end of September and the pound fell to record lows against the dollar, but said there is "a very dicey situation globally".

"I speak to Number 10, the PM all the time, and we are totally focused on delivering the growth plan," he said.

Pushed on whether there will be any more reversals of policies in the mini-budget, Mr Kwarteng said: "I am totally focused on the growth agenda."

Last week, after open revolt from Tory MPs and a surge in support for Labour in the polls, Ms Truss and Mr Kwarteng abandoned the plan to abolish the highest 45% tax rate.

Sky News understands discussions are under way in Downing Street over whether to scrap some of the contentious proposals which remain in the chancellor's tax-cutting mini-budget.

The proposed changes to corporation tax and dividend tax are those understood to be under discussion.

Downing Street insisted earlier on Thursday that there will be no more U-turns on policies in the government's tax-cutting mini-budget despite pressure from Conservative MPs for changes to be made.

Asked to confirm there would be no further reversals, the prime minister's official spokesman 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."

Ms Truss faces open revolt in her party over the £45bn package of unfunded tax cuts in the mini-budget, which unleashed chaos in the markets when it was announced last month.

Former home secretary Priti Patel became the latest senior Tory to suggest the government could be forced into another U-turn, telling Sky News "market forces" could make a reversal on corporation tax cuts unavoidable.

Giles Wilkes, a senior fellow at the Institute of Government and a former special advisor to Theresa May, has also said a U-turn "might be the only way the government can actually get out of this self-made disaster".

He said Liz Truss is facing possibly the most difficult situation a prime minister has been in this side of the Second World War".

"I can't think of somebody who's put themselves into such a position where they're forced to defend something that nobody else thinks is defensible, and forced to contemplate really tough measures like slashing benefits or slashing important government spending budgets in order to try to keep a policy that nobody else believes can go on the road," he said.

"It's an incredibly difficult position, but right now, she's playing for survival stakes. She has to think, 'what do I need to throw overboard in order to keep things going?' And if it's pretty much all the policies announced in the so-called mini budget, then that's the only thing I can think she can do."

The chancellor will set out his debt-cutting plan in more detail on 31 October, having bowed to pressure to bring the date forward from 23 November given the economic turbulence.

Earlier on Thursday, James Cleverly, the foreign secretary, refused to say there would be no more reversals.

He told Sky News the Halloween statement would give "a more holistic assessment of the public finances and our response to the global headwinds that every democracy, every economy in the world is facing".

Pressed on the plan to axe the increase in corporation tax from 19% to 25% in April, Mr Cleverly said it is "absolutely right" the government helps businesses to "stay competitive" and "stay afloat".

The Treasury had vowed to reduce the rate of income tax on dividends by 1.25 percentage points.

Mr Kwarteng is meeting with International Monetary Fund (IMF) leaders in Washington DC today, after the institution's chief economist said tax cuts threatened to cause "problems" for the UK economy.

Speaking at a press conference in Washington, the managing director of the IMF said it is sometimes right for a "recalibration" of policies as she was questioned over reports of further U-turns after the mini-budget market chaos.

Kristalina Georgieva said: "Our message to everybody, not just the UK, is that at this time, fiscal policy should not undermine monetary policy."

Meanwhile, in a post on social media on Thursday, former Conservative chancellor George Osborne questioned why Ms Truss and Mr Kwarteng would wait for the chancellor's statement on 31 October to perform an "inevitable U-turn" on their mini-budget.

On Wednesday, Mel Stride, the Tory chairman of the Commons Treasury Committee, said that given Ms Truss's commitments to protect public spending, there was a question over whether any plan that did not include "at least some element of further row back" on the tax-slashing package can reassure investors.

While David Davis, the Tory former minister, called the mini-budget a "maxi-shambles" and suggested reversing some of the tax cuts would allow Ms Truss and Mr Kwarteng to avert leadership challenges for a few months.
