Boris Johnson’s leadership has been plunged deeper into crisis by the resignation of four top aides within a few hours – including an ally of 14 years who quit in protest at his “scurrilous” smear linking Sir Keir Starmer with the paedophile Jimmy Savile.
In a scathing resignation letter, policy chief Munira Mirza said there was “no fair or reasonable basis” for Monday’s attack and made clear that Mr Johnson had resisted pleas from advisers to apologise.
