U.K. Prime Minister Boris Johnson confirmed Thursday that he will resign as leader of the Conservative Party and step down as prime minister once a replacement is selected.
How it happened: Dozens of ministers in Johnson's government resigned over the past 24 hours as a cascade of scandals finally caught up to the prime minister. In remarks outside 10 Downing Street, Johnson said this was a "painful" moment, and noted that he'd fought hard to avoid it.
