Supreme Court rules Act of Parliament needed to trigger Article 50 and leave UK

The Supreme Court ruled today by a majority of 8-3 that an Act of Parliament is needed for the UK Government to trigger Article 50 and formally begin the process of leaving the EU. Giving the leading judgment the President of the Court, Lord Neuberger, emphasised that the judgment was not about whether the UK should leave the EU but what was necessary to respect the UK’s constitutional arrangements.
