Boris Johnson would have faced a 90-day suspension from the House of Commons after he committed “repeated contempts” of Parliament with his partygate denials, the Priviliges Committee has found.

The Privileges Committee’s recommended suspension for acts, including deliberately misleading MPs, would have paved the way for a by-election for the former prime minister if he had not resigned in anticipation.

Mr Johnson hit out at what he called a “deranged conclusion”, accusing the Tory-majority group of MPs he has repeatedly sought to disparage of lying.
