UK Government vows to deliver article 50 pledge despite Supreme Court reverse

The Government's defeat in a historic court battle over Brexit will not derail Theresa May's plan to start negotiations on withdrawal from the EU by the end of March, Downing Street has said.

By a majority of eight to three, judges at the Supreme Court rejected the Government's argument that Mrs May could use prerogative powers to trigger the talks under Article 50 of the EU treaties, but must first seek Parliament's approval.
