Four Johnson aides quit in fallout from Downing Street parties

Policy chief Munira Mirza was first to go, followed shortly by Jack Doyle, Dan Rosenfield and Martin Reynolds

Four of Boris Johnson's key staff have quit as the fallout from the Downing Street party scandal continued to shake his hold on government.

Johnson's longstanding policy chief Munira Mirza was the first to go, using a stinging resignation letter to accuse the prime minister of scurrilous" behaviour when he falsely linked Keir Starmer to the failure to bring paedophile Jimmy Savile to justice.
