Parliament overwhelmingly rejects Brexit plan

British lawmakers voted 432 to 202 against Prime Minister Theresa May’s plan to leave the E.U. It was the biggest defeat in the House of Commons for a prime minister in recent history, and it appeared to rip the mast off the ship of state.

Impact: Much of Mrs. May’s own party deserted her, and her plan looks less likely than ever to be realized. With a historically straitjacketed Parliament now seizing control of the situation, a new kind of British governance is taking shape, with a diminished prime minister and a dynamic of gridlock reminiscent of America.

What’s next? The opposition Labour Party leader, Jeremy Corbyn, put forward a motion of no confidence in Mrs. May, which Parliament will debate and vote on Wednesday. If the motion is successful, a new government will need to be formed in 14 days. But Mrs. May is seen as somewhat likely to survive that vote.
