Boris Johnson “waved aside” objections to let the No10 party in May 2020 go ahead, his ex-aide claims.
Dominic Cummings says he and others would swear on oath that top officials warned the event was against the rules. It would mean the PM lied when he told the Commons he thought it was a work event.
Johnson sparked disbelief last week at PMQs when he apologised for the May 20, 2020, event but claimed he “implicitly believed” it was work related.
