Suella Braverman has accused Rishi Sunak of having “manifestly and repeatedly failed to deliver” on key policies, in an incendiary resignation letter after being sacked as home secretary.
Mrs Braverman, one of the leading figures on the right of the Tory party, urged Mr Sunak to “change course urgently”, telling him he has led the Conservatives to “record election defeats” and that his “resets have failed and we are running out of time”.
In a three-page broadside, she accused the Prime Minister of “betrayal” over a promise to stop small boat crossings.
She said Mr Sunak had not lived up to his promise to do “whatever it takes” to stop small boat crossings by failing to override human rights concerns about the Rwanda plan.
Monday's dramatic reshuffle - which saw Lord David Cameron appointed Foreign Secretary and Mrs Braverman sacked - has angered some on the Tory right. Allies of ousted Mrs Braverman accuse the Prime Minister of abandoning 2019 voters, in his bid to revive his electoral fortunes.
But earlier on Tuesday, Mr Sunak hailed his "strong and united team" at his first Cabinet meeting following the reshuffle, and promised "big, bold decisions that will drive change".
