Prime Minister Theresa May has signed the letter to European Nation that will formally begin the UK's departure. The letter will be delivered to the European Council president Donald Tusk on Wednesday, as it will give official notice under article 50 of the Lisbon treaty.

The Prime Minister will make a statement in the Commons and tell the MP's this marks "the moment for the country to come together." This follows the June referendum that resulted in a vote to leave the European Union. The letter will be delivered to Mr. Tusk at 12:30 British Standard Time by the British Ambassador Sir Tim Barrow to the EU.

Theresa May will chair a cabinet meeting in the morning and confirm the countdown to the UK's departure from the EU. She will later on promise to represent every person in the whole United Kingdom during the negotiations, this also includes EU nationals whose status after Brexit has yet to be settled as per BBC.

Attempting to move on the divisions of the referendum, the Prime Minister will make various statements. She will add "We are one great union of people and nations with a proud history and bright future." Now that the decision has been made to leave the EU, it is time for UK to come together.

Jeremy Corbyn the Labor Leader stated that the party had respected the decision to leave the EU, and it will certainly hold the government to account on every step of the way. Mr. Corbyn further said that Britain is going to change as a result. He also warned if Mrs. May does not secure protection for workers rights it would turn out to be a national failure of historic proportions.

The Article 50 gives both the sides to reach agreement, until and unless both agree to extend the deadlines for talks, the UK will leave on 29 March 2019.
