London: British lawmakers overwhelmingly rejected Prime Minister Theresa May’s divorce deal with the European Union on Tuesday, plunging the Brexit process into chaos and triggering a no-confidence vote that could topple her government.

The defeat was widely expected, but the scale of the House of Commons’ vote — 432 votes against the government and 202 in support — was devastating for May’s fragile leadership.

It followed more than two years of political upheaval in which May has staked her political reputation on getting a Brexit deal and was the biggest defeat for a government in the House of Commons in modern history.
Moments after the result was announced, May said it was only right to test whether the government still had lawmakers’ support to carry on. Opposition leader Jeremy Corbyn quickly obliged, saying May’s government had lost the confidence of Parliament.

Lawmakers will vote Wednesday on his motion of no-confidence. If the government loses, it will have 14 days to overturn the result or face a national election.

Although May lacks an overall majority in Parliament, she looks likely to survive the vote unless lawmakers from her Conservative party rebel. Northern Ireland’s Democratic Unionist Party, which props up May’s government, said it would support her.

“The House has spoken and the government will listen,” May said after the vote, which leaves her Brexit plan on life support just 10 weeks before the country is due to leave the EU on March 29.

The Parliament has given the government until Monday to come up with a new proposal.

She faces a stark choice: Steer the country toward an abrupt “no-deal” break with the EU or try to nudge it toward a softer departure. Meanwhile, lawmakers from both government and opposition parties are trying to wrest control of the Brexit process from a paralysed government, so that lawmakers by majority vote can specify a new plan for Britain’s EU exit.

But with no clear majority in Parliament for any single alternate course, there is a growing chance that Britain may seek to postpone its departure date while politicians work on a new plan — or even hand the decision back to voters in a new referendum on EU membership.

May, who had postponed a vote on the deal in December to avoid certain defeat, had implored lawmakers to back her deal and deliver on voters’ decision in 2016 to leave the EU.

But the deal was doomed by deep opposition from both sides of the divide over UK’s place in the bloc. Pro-Brexit lawmakers say the deal will leave Britain bound indefinitely to EU rules, while pro-EU politicians favor an even closer economic relationship with Europe.

The most contentious section of the deal was an insurance policy known as the “backstop” designed to prevent the reintroduction of border controls between the UK’s Northern Ireland and EU member Ireland. Assurances from EU leaders that the backstop is intended as a temporary measure of last resort completely failed to win over many British skeptics.

Two and a half years after the referendum, Britain remains divided over how, and whether, to leave the EU.

Frustrated EU leaders called on May to make her intentions clear on the future of Brexit.
