UK Prime Minister, Theresa May has signed the letter to begin the country’s
departure from the European Union.
May signed Article 50 of the Lisbon Treaty, which will be delivered to European Council president Donald Tusk later.
Mrs May’s letter will be delivered at 12:20 BST on Wednesday by the British ambassador to the EU, Sir Tim Barrow.
The Prime Minsiter is also set to make a statement to MPs confirming the countdown to the UK’s departure from the EU is under way.
She will promise to “represent every person in the whole United Kingdom” during the negotiations – including EU nationals, whose status after Brexit has yet to be settled.
“It is my fierce determination to get the right deal for every single person in this country,” she will say.
“For, as we face the opportunities ahead of us on this momentous journey, our shared values, interests and ambitions can – and must – bring us together.”
