British Prime Minister Boris Johnson has announced his resignation, saying that he is “sad” to be “giving up the best job in the world,” in a speech to the nation Thursday outside No. 10 Downing Street, his official residence.

It comes after more than 50 members of his own government resigned in the past 48 hours in open revolt against his leadership. Ministers and aides, including several members of his Cabinet, said they no longer had faith in his leadership after a series of scandals, the latest involving an ally accused of sexual misconduct.

Johnson insisted he would continue to serve as prime minister until his successor is chosen — despite criticism from many lawmakers from his own party who insisted he should step down now.
