Supreme Court says it will give Brexit trigger case ruling on Tuesday

By Michael Holden LONDON (Reuters) - The United Kingdom's Supreme Court will deliver its ruling next Tuesday on whether Prime Minister Theresa May can begin leaving the European Union without parliament's assent, potentially giving lawmakers a chance to have a vote on Brexit. May has said she would trigger Article 50 of the EU's Lisbon Treaty, the formal means of exiting the bloc, by the end of March and on Tuesday detailed her vision for a clean break with the EU by quitting its single market.
