British Prime Minister Theresa May won a crucial Brexit vote in Parliament on Wednesday, keeping her divided government’s plans to end more than 40 years of U.K. partnership with the European Union on track.
After pro-EU Conservative lawmaker Dominic Grieve said he would support the government’s proposal for a “meaningful vote” in Parliament on Britain’s exit, a potential rebellion that could have undermined Ms. May’s authority was averted.
The Prime Minister adopted a high-risk strategy by facing off with rebels in her Conservative Party, and it paid off. The House of Lords later approved the bill, paving the way for it to become law after gaining royal assent from the Queen.
Ms. May said in a statement that the bill’s passage was a crucial step in delivering Brexit, and more details of proposed future links with the EU would be published in the coming weeks.
But the battle over Ms. May’s Brexit blueprint may be a taste of things to come. She needs to get several other bills through Parliament to prepare Britain for life outside the EU, a momentous change to its trading and political relationships after decades in the bloc.
Some of her opponents on Brexit may simply have decided to keep their powder dry for later fights on issues such as future trading ties and customs arrangements with the bloc before Britain’s scheduled departure in March next year.
Six Conservatives still voted against the government. But for now, May will be relieved to have overcome another potential crisis over her proposal for the role of Parliament, should she fail to negotiate an exit agreement with the EU or if lawmakers reject any deal she returns with from Brussels.
“There was a great point of principle here, which was that the government has to be able to be free to negotiate and we have to be able to hold out in our negotiations the prospect of no deal, otherwise all the advantage would have been with the EU side,” trade minister Liam Fox told the BBC.
Other Conservatives agreed. “It strengthens our hand,” said one, while opposition lawmakers described the vote as disappointing.
Sterling rose to a session high against the euro and climbed against the U.S. dollar after Ms. May won the rare victory, one that is expected to give the Prime Minister a firmer footing when she travels to Brussels next week for an EU summit.
Talks with the bloc have all but stalled, with Ms. May’s top team of ministers at odds over plans for future trading relations with the EU, which businesses complain makes them unable to plan their investment decisions.
Before his about-turn, Mr. Grieve had argued that government promises did not hand Parliament enough control to prevent the “chaos” that could follow Britain crashing out of the EU without a deal.
Mr. Grieve seemed to have won over several fellow Conservatives but after days of lobbying by party officials, he seemed to have put his concerns aside. He told the House of Commons he now saw the need to take account of Ms. May’s concerns over the state of the negotiations. He also said he had been reassured by a statement saying it was up to the parliamentary speaker to grant lawmakers greater influence over ministers in the event of no deal.
“And in the circumstances that might follow a no deal, which would undoubtedly be one of the biggest political crises in modern British history, if the house wishes to speak … the House has the power to do it,” Mr. Grieve said.
With his words, Ms. May was able to enjoy victory in a Parliament that is stacked against her since she lost her majority in an ill-judged election gamble last year.
But businesses are still seeking more certainty. “My biggest worry about Brexit is that I don’t know what we are planning for,” Juergen Maier, the U.K. chief executive of German engineering giant Siemens said.
“We need to put something in place quickly that works and if that is not possible, and until that point, then we have to just default to staying in the customs union.”
