The wait is over - Parliamentary approval is required to trigger Article 50. The most senior judges in the country have ruled that the government will now need to bring a bill forward for Parliament to approve. The next question is, will this requirement delay Theresa May's timetable for triggering Article 50 or can any amendments to the proposed Bill be resolved by the end of March?
The Supreme Court has dismissed the government's appeal in its long-awaited judgment in the Article 50 case this morning. The court voted by a majority of eight to three to dismiss the case, meaning MPs must be given a vote before the Brexit process can begin. However, it also said it had unanimously decided devolved parliaments in Scotland and Wales do not need to be consulted before Article 50 is triggered. The case, which was heard by all 11 of the Supreme Court justices in December, was an appeal by the government from an earlier High Court decision, in which a trio of judges ruled parliament must give the thumbs up before Article 50 can be triggered.
