UK high court has ruled that the government cannot trigger Article 50 without parliamentary approval

The UK High Court has ruled that the Government does not have power to trigger Article 50 without parliamentary approval. The judge stated that government's arguments are "contrary to fundamental constitutional principles of the sovereignty of parliament". The case was brought to court by a group calling itself People’s Challenge.

The government have said today that they will appeal the decision in the Supreme Court, which will most likely hear the case on 7 December 2016.

I think the ruling party has a majority of only around 9 or 10 members in parliament, which means Brexit could be rejected by MP vote or the “Remain” MPs within the ruling party could ask for a bigger say in the how the exit strategy is formulated.

The pound has strengthened by almost 1% today and has risen by 1.5% against the Dollar in the past two days.

The PM said she would trigger Article 50 in March 2016. All of our economic models still assume that Brexit goes ahead.
