UK Invokes Article 50

Date: March 29, 2017 • Location: Rome, Italy

Prime Minister Theresa May invokes Article 50 of the Treaty on European Union, formally beginning the United Kingdom's withdrawal from the European Union.

The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet, and selects its ministers. Modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, so they are invariably members of Parliament.
