Britain is set to formally file for divorce from the European Union, ending a 44-year relationship following the decision made by U.K. voters in a referendum nine months ago.
Prime Minister Theresa May is due to tell House of Commons Wednesday afternoon that she has invoked Article 50 of the EU’s key treaty, the trigger for a two-year countdown to Britain’s exit.
At the same time, Britain’s EU envoy, Tim Barrow, will hand-deliver a letter from May, which she signed Tuesday at her 10 Downing St. office, to EU Council President Donald Tusk.
May’s office says she will tell lawmakers that the U.K. is embarking on a “momentous journey” and should unite to forge a “global Britain.”
