Brexit has begun. On Wednesday, British Prime Minister Theresa May sent an historic letter triggering Article 50 of the Lisbon Treaty, formally initiating the country's withdrawal from the European Union (EU). In a statement to the House of Commons, May called this an "historic moment from which there can be no turning back." In response, European council president Donald Tusk said, "there is no reason to pretend this is a happy day." May's letter comes after the British public voted in a June 2016 referendum for the country to leave the EU. In this hour, we'll discuss what Brexit might mean for the U.K and the countries staying in the EU, and preview what will likely be two years of exit negotiations.
