The U.K. will trigger the Brexit process next Wednesday
Prime Minister Theresa May will trigger Article 50 on March 29, which formally begins the United Kingdom's exit from the European Union.
What's next: Negotiations over the exit, which can expected to last two years. Departing a single market won't be simple, and May has already said she wants a "hard" Brexit, rather than leaving one foot in the door. At this pace, the U.K. will be fully split from the E.U. by early 2019.
