Four of Boris Johnson's most senior aides have resigned in just 24 hours, rocking the PM's inner circle.
Policy chief Munira Mirza, director of communications Jack Doyle, principal private secretary Martin Reynolds and chief of staff Dan Rosenfield all quit their Downing Street jobs on Thursday.
There was pressure on both Mr Doyle and Mr Reynolds to resign, after it was revealed they were involved in Downing Street gatherings during lockdown.
