Sir Keir Starmer is facing a backlash over the 'needlessly cruel' treatment of female aides in Downing Street.
Nin Pandit, the Prime Minister's principal private secretary (PPS), is leaving the role just 10 months after being appointed by Sir Keir as his gatekeeper.
She is the third senior staff member to be replaced by Sir Keir in less than a year.
It follows the departure of Sue Gray as the PM's chief of staff in October last year, while Sir Keir also saw his communications chief, Matthew Doyle, resign in March.
News of Ms Pandit's exit was accompanied by a brutal briefing to the BBC that Sir Keir had become concerned she was 'ineffective' as his PPS.
