The Britain Government has said that it will fight a high court ruling that could frustrate its timetable for Brexit.
Brexit Secretary David Davis said that 17.4 million leave voters had given the government the biggest mandate in history to leave the European Union.
Britain's plans to leave the European Union hit a large speed bump yesterday when the high court ruled that the government cannot start exit negotiations without a vote in Parliament.
It is expected that that Supreme Court will next month hear the government's plea.
Yesterday's ruling opens a major constitutional battle over the balance of power between Parliament and the govesrnment.
Prime Minister Theresa May has said that she will use centuries-old powers known as royal prerogative to invoke Article 50 of the EU treaty, which launches two years of exit negotiations, by the end of March.
The powers - traditionally held by the monarch but now used by politicians - enable decisions about international treaties and other issues to be made without a vote of Parliament.
