LONDON - 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 British 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 May's authority was averted.

May adopted a high-risk strategy by facing off with rebels in her Conservative Party, and it paid off. The upper house of parliament later approved the bill, paving the way for it to become law after gaining formal "Royal Assent" from the Queen.

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 the EU withdrawal bill, her Brexit blueprint, may be a taste of things to come. May 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.

Talks with the bloc have all but stalled, with 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.
