Pound rises after UK government loses Article 50 case
On Thursday the High Court ruled in a land mark case that MPs must hold a vote before the clause in the Lisbon treaty is activated for a two-year clock on Brexit negotiations with the EU.
Prime Minister Theresa May has previously said she will trigger Article 50 by the end of March 2017.
The ruling said: "The court does not accept the argument put forward by the government. There is nothing of the 1972 Act to support it.
"In the judgement of the court the argument is contrary both to the language used by Parliament in the 1972 Act and to the fundamental constitutional principles of the sovereignty of Parliament and the absence of any entitlement on the part of the Crown to change domestic law by the exercise of its prerogative power. The court accepts the principle argument of the claimants.
"For the reasons set out in the judgement, we decide that the government does not have the power under the crown's prerogative to give the notice pursuant to Article 50 for the UK to withdraw from the European Union".
The government said it was "disappointed" by the ruling and will appeal the decision to the Supreme Court for a hearing expected on December 7. ■
