British Prime Minister Theresa May secured a symbolic victory on Brexit on Wednesday after MPs agreed not to delay her plans to begin exit talks by the end of March, although she had to promise to give them more details of her negotiating strategy.

Lawmakers voted 461 in favour of supporting May's timeline to trigger Article 50 of the European Union's Lisbon Treaty, which will trigger divorce negotiations with Brussels.

A total of 89 MPs voted against the non-binding motion, with the results announced in parliament.

In an amendment to an opposition motion in parliament, May agreed to provide further details on her negotiating strategy before triggering Article 50.
