Britain’s exit from the European Union was in disarray after the implosion of Prime Minister Theresa May’s Brexit strategy left her under pressure from rival factions to leave without a deal, go for an election or forge a much softer divorce.

A third defeat of May’s divorce deal, after her pledge to quit if it was passed, left one of the weakest leaders in a generation grappling with a perilous crisis over Brexit, the United Kingdom’s most significant move since World War Two.
