A judge will rule on whether Boris Johnson's plan to shut down the UK Parliament for five weeks ahead of Brexit is lawful.

The case was brought to the Court of Session in Edinburgh by a cross-party group of 75 parliamentarians, who argued the PM exceeded his powers.

The government said the issue should be a political, rather than a legal, one.

Lord Doherty heard submissions from both sides on Tuesday, and will deliver his ruling on Wednesday morning.
