A letter demanding Rishi Sunak step down as Prime Minister has been signed by more than 5,000 Tory supporters in just 24 hours.
The Conservative Post, aimed at grassroots Tory members, put up a letter on its site demanding that Sunak quit as party leader and Prime Minister.
The letter was signed by 5,027 people in the first 24 hours.
It urged Tory backers and other "patriots" to sign, saying: "Lord Frost warned if MPs don't act now 'there will soon only be smoking rubble left,' a sentiment echoed by MP Simon Clark who called to replace Sunak immediately 'or face a decade of decline under Starmer.'"

The letter claims that it is not too late to stop Labour from winning the election, saying: "We do still have time to win the next election and keep Labour out of No 10 but many of us feel Rishi Sunak needs to go."
This comes as the party battles disastrous polling, with most polls putting the Conservatives more than 20 points behind Labour.
Despite Wednesday's Spring Budget, which saw the Chancellor unveil a further 2p National Insurance cut, polling published by YouGov for the Times put the Tories 27 points behind Labour - suggesting they received no poll bounce from the fresh measures.
And a poll published on Monday, ahead of the budget, saw the Tories fall to a record low in their approval ratings.
Support for the party fell to a low of 20 per cent, the Ipsos poll showed. This is a seven point drop from January.
The survey marks the lowest result since Ipsos regular poll tracker began in 1978.
Hunt's budget, unveiled on Wednesday, saw him attempt to win over voters by announcing a 2p cut to national insurance.
Leaving income tax untouched, Hunt was keen to stress the benefits of the combined NI cuts announced over the last two budgets - saying it will amount to a £900 saving for the average employee.
The Chancellor also suggested National Insurance payments could be scrapped entirely, describing the levy as "particularly unfair". He said his "long-term ambition" is to end the system of double taxation.
LATEST DEVELOPMENTS:
Hunt also froze both alcohol and fuel duty until 2025, along with the creation of a "British ISA" which will allow an additional £5,000 annual investment in UK equity.
The Chancellor allocated £3.4 billion in investment aimed at improving NHS productivity, something he said will "unlock £35 billion of savings". He announced plans to get rid of the "outdated" non-dom status, instead replacing the regime with a "modern, simpler and fairer residency-based system" from April 2025.
Hunt also extended child benefits to hundreds of thousands of middle-income families, increasing the high-income child benefit charge threshold from £50,000 to £60,000.
