More than 80 MPs are plotting to stage a Parliamentary vote calling for a second Brexit referendum.

In a move that prompted anger from Conservative ministers a coalition of MPs led by Tim Farron, the Liberal Democrat leader, said that they now intend to force a vote calling for another referendum of the terms of Britain’s exit from the EU.

Theresa May’s Government is appealing a High Court ruling which stated that she must get Parliament’s approval before triggering Article 50, which formally begins the Brexit negotiations with Brussels.
