UK foreign secy Boris Johnson resigns in mounting Brexit crisis

British Foreign Secretary Boris Johnson, a charismatic and divisive cheerleader for Britain's exit from the European Union, resigned Monday, adding to a crisis over Brexit that threatens to tear apart Prime Minister Theresa May's government. May's office said in a terse statement that the prime minister had accepted Johnson's resignation and would name a replacement soon. Johnson, one of the best-known and most flamboyant members of the government, quit just hours after the resignation late Sunday of Brexit Secretary David Davis, the government's top Brexit official.
