Lawmakers from the Conservative Party Theresa May on Wednesday initiated a vote of a vote of no confidence in the prime minister amid a sharp increase in uncertainty around Britain’s exit from the European Union.

According to Graeme Brady, chairman of the Conservative Party’s parliamentary committee, which has the right to run the procedure, voting will take place between 6 pm and 8 pm local time in the House of Commons.

Voting results will be announced as soon as possible, he said.
