Boris Johnson would have known if a party was being held by staff in Downing Street, his former chief aide has said, despite allies insisting the Prime Minister could not be expected to know what was happening in every room.

Conservative chief whip Mark Spencer insisted Downing Street staff “were not drinking alcohol” and partying during Covid restrictions after it emerged the Prime Minister’s press chief addressed staff at one event last Christmas.
