In a historic moment in Britain’s history, Prime Minister Theresa May has officially begun the process of Britain leaving the European Union, known as Brexit. This morning, British diplomat Tim Barrow handed the letter to Donald Tusk, the president of the European Council. The letter, known as Article 50, will now trigger two years of negotiations about the terms of Britain’s departure from the European Union. The first minister of Scotland, Nicola Sturgeon, is now seeking to hold a referendum on whether Scotland should declare independence from Britain in order to stay in the EU. British voters narrowly approved Brexit in a shocking referendum in late June, leading to the resignation of British Prime Minister David Cameron.
