Politics LIVE: Pressure mounts on Boris Johnson after mass Downing Street resignations

Boris Johnson’s administration was plunged into further turmoil after four of his closest aides resigned

Boris Johnson’s administration was plunged into further turmoil by a host of resignations after four senior aides quit Downing Street on the same day.

In a torrid day for the PM, his chief of staff, principal private secretary, director of communications and policy chief quit Downing Street within hours of one another.

Munira Mirza, the former director of the No 10 policy unit and one of Mr Johnson’s most loyal and longstanding advisers, walked out after attacking the Prime Minister’s use of a “scurrilous” Jimmy Savile smear against Labour leader Sir Keir Starmer.

There also appeared to be division within the Treasury over the Savile comments as Chancellor Rishi Sunak admitted he would not have used the jibe, while one of his ministers later defended Mr Johnson suggesting it was a “perfectly reasonable remark”.

Meanwhile, Northern Ireland First Minister Paul Givan has announced his resignation from Stormont’s powersharing Executive.

The move by the Lagan Valley MLA is part of the DUP’s escalating protest strategy against Brexit’s Northern Ireland Protocol.
