Liz Truss has just 10 days to save her premiership, former cabinet minister Grant Shapps has warned.
He said the prime minister has a “limited period of time to turn things around” after the government made a U-turn on plans to abolish the 45p income tax.
MPs fearing losing their seats in the next general election may think that they “might as well roll the dice” on a new leader just a month into Ms Truss’ leadership, Mr Shapps said.
His comments came after home secretary Suella Braverman said she supported the scrapping of the 45p tax, and claimed that Tory members have “staged a coup and undermined the authority of the Prime Minister”.
Ms Truss has refused to rule out bringing back her plan to scrap the 45p tax in the future, even though the proposal spooked the markets and caused a split in the Conservative Party.
Asked by the BBC if she still thinks it was “a good idea”, she said: “I would like to see the higher rate lower. I want us to be a competitive country, but I have listened to feedback”.
