Theresa May suffered a second defeat in two days as Parliament asserted its authority over Brexit.

MPs voted by 308 votes to 297 on an amendment to force the Prime Minister to return to the House and make a statement about a “plan B” within three days if she loses.

John Bercow, the Speaker, was accused of a "procedural stitch-up" as he accepted the amendment which aims to effectively tie Theresa May's hands and give more power to Parliament if she loses her Brexit vote.

A cross-party group of MPs, led by the Conservative Dominic Grieve, tabled an amendment to cut down the amount of time Mrs May has to find a solution after losing her vote.

Previously, the Government had 21 days to make the statement.
