Supreme court rules Brexit cannot begin without vote from Parliament
While Parliament will have a say the court ruled that the Scottish Parliament and Welsh and Northern Ireland assemblies will not have a say stating "Relations with the EU are a matter for the UK government."
During the Supreme Court hearing, campaigners argued that denying the UK Parliament a vote was undemocratic and a breach of long-standing constitutional principles. They said that triggering Article 50 of the Lisbon Treaty - getting formal exit negotiations with the EU under way - would mean overturning existing UK law, so MPs and peers should decide.
Reading out the judgement, Supreme Court President, Lord Neuberger, said: "By a majority of eight to three, the Supreme Court today rules that the government cannot trigger Article 50 without an act of Parliament authorising it to do so."
"The UK's constitutional arrangements require such changes to be clearly authorised by Parliament."
