In a shock announcement, Prime Minister Theresa May on Tuesday called for an early general election to be held June 8 to seek a strong mandate as she negotiates Britain’s exit from the European Union.

Standing outside 10 Downing Street, May said she would ask the House of Commons on Wednesday to back her call for an election, three years before the next scheduled date in May 2020.

She said that since Britons voted to leave the EU in June, the country had come together, but politicians had not. She said the political divisions “risk our ability to make a success of Brexit.”

At present, May’s governing Conservatives have 330 seats in the 650-seat House of Commons. May said that, “our opponents believe that because the government’s majority is so small, our resolve will weaken and that they can force us to change course” on leaving the EU.
