Leading business figures and Conservative MPs are putting pressure on the UK prime minister to step down after a series of damaging U-turns that have shredded her credibility.

Critics said that the decision to appoint Jeremy Hunt as chancellor had failed to reassure markets and the City. Her allies warned that those trying to remove her were forcing the Conservatives towards a general election.

After Friday's sell-off when investors warned that the scrapping of the corporate tax cut was not enough, the market was bracing for more turbulence on Monday.

Leading City figures and three Conservative MPs have called for the resignation of the Prime Minister.

The PM had lost the confidence of business and investors according to Stuart Rose. He said that she was a busted flush. The confidence of business, investors, electorate and colleagues in the party is what the prime minister needs to have. She doesn't have anything of these.

Dame Alison Carnwath, former chair of Land Securities and senior adviser at investment bank Evercore, said that Truss had no mandate, insufficient support in parliament, incomprehensible economic policies and lacks charisma. She said that Truss should be the shortest serving prime minister of all time.

Terra Firma's founder said that Truss should leave as soon as possible.

He said that a grown-up needs to take over the Conservative leadership and become a prime minister who represents everyone.

Thesacking of Kwarteng is one of the most cowardice political acts committed by a prime minister since Britain had a form of democracy, according to Hands.

Crispin Blunt, a former prisons minister, said that the game was over and that the succession had to be managed. Andrew Bridgen and Jamie Wallis are Conservative backbenchers.

It would take time for the UK to rebuild market confidence after the fiscal plans were announced, according to investors.

James Athey, a bond fund manager at Abrdn, said that many investors would need some time to determine if gilt prices have found a base.

Several cabinet ministers have begun to ring around MPs in a bid to drum up support for potential leadership candidates, including supporters of defence secretary Ben Wallace.

The prime minister's allies likened theplotters to the people who were campaigning for a second referendum.

A pro-Truss Conservative party figure said that those who plot against the government don't care about the economy or the markets. Political instability affects markets.

A new leader wouldn't have acoronation, according to the official. There will be an early general election if there is a repeat of the summer leadership contest. The Conservatives owe it to the British people to focus on them. The British people are the ones who the plotters work for.

On Sunday Hunt was locked in talks with Truss about a new economic plan to be presented on October 31 which is likely to involve further U-turns on tax cuts as well as spending cuts.

Hunt said on Sunday he was not going to take anything off the table.

The party can't get rid of her for fear of losing more credibility. He said he would wait for the next leader to decide if he would donate again. Hunt shouldsteady the ship but he was not happy with the U-turn on corporation tax.

Rose believes that the rate of corporation tax is less of an issue than a plan to allow companies to invest. The CEOs of the country are working on their financial year plans. We are facing a lot of challenges. The companies just want a runway.

In a rare intervention on domestic UK politics, US president Joe Biden said last month's mini-Budget was a mistake. He said that it was up to Great Britain to decide.

The U-turn in corporation tax is expected to lead to a more significant recession in the UK, according to Goldman.
