Boris Johnson Clings On to Prime Minister Role as More U.K. Lawmakers Quit

LONDON—British Prime Minister Boris Johnson clung to power in Downing Street on Wednesday evening, refusing to quit following an extraordinary standoff with his Conservative Party that saw a wave of ministers resign and members of his own cabinet implore him to step aside.

In a frenetic day in Britain’s Parliament, Mr. Johnson sought to ride out a rebellion as a long line of Conservative Party lawmakers stated they no longer had confidence in the prime minister following a series of scandals and questions about the British leader’s integrity.
