Looking at UK Supreme Court ruling
Tomorrow the UK Supreme Court will announce its decision, if the government needs to have a Parliamentary vote or not, to trigger the Article 50 (beginning of Brexit).
“After Prime Minister May's speech last week, the decision may have lost some of its ability to roil the markets. May reassured that Parliament would vote on the final agreement”, said analysts from Brown Brothers Harriman.
According to them, there is little doubt a majority will vote to trigger Article 50 in the Parliament but they warn that a failure to do so, would likely spark a political crisis. “Northern Ireland will go to the polls on March 2. An anti-Brexit parliament could still frustrate May's timetable, and Scotland independence efforts may be fanned by the UK government's position.”
