Prime Minister pledges to trigger Brexit by end of March 2017

Theresa May has vowed to trigger Brexit by the end of March 2017 even if the UK's highest court decides parliamentary approval is required.

The Prime Minister said the Government will "respect" the verdict of the independent judiciary, with the Supreme Court to announce its decision "as quickly as possible" in the new year.

Labour leader Jeremy Corbyn called on Mrs May to make sure her new year's resolution includes a "commitment to build better relations" with the UK's European partners to ensure she can secure the best deal possible.
