Fighting back tears, British Prime Minister Theresa May has said she would quit, triggering a contest that will bring a new leader to power who is likely to push for a more decisive Brexit divorce deal.

Prime Minister Theresa May yesterday vowed to win a vote of no confidence triggered by angry Brexit supporters in her Conservative Party, saying her ouster would jeopardise Britain's divorce from the European Union.

British Prime Minister Theresa May says she will lead a minority government backed by a small Northern Irish party after she loses an election gamble days before the start of talks on Britain's departure from the European Union.
