Boris Johnson is prepared to launch a legal action in his attempts to ensure Britain can leave the European Union this month with no deal.

Several Government sources have told The Daily Telegraph that the Prime Minister is willing to go to the Supreme Court in an effort to avoid having to write a letter asking for a delay to Brexit, as set out in the Benn Act.

It raises the possibility that Mr Johnson could give evidence in the court case in an attempt to persuade judges in person against forcing him to ask the EU for a Brexit delay.
