Former British Prime Minister Boris Johnson announced Friday evening to hand over his mandate as an MP. The 58-year-old former prime minister said his decision was effective immediately, triggering a by-election.

A year after being driven out of Downing Street by his majority, Boris Johnson remained under a parliamentary inquiry to determine whether he had misled Parliament in the "partygate" affair. He accused the commission of having produced a report that has not yet been published, "riddled with inaccuracies and reeling from prejudice", without giving it "any formal opportunity to challenge what they say"
