On the 29 March 2017, Prime Minister Theresa May wrote to European Council President Donald Tusk to notify him of the UK’s intention to leave the EU. The letter was delivered by Sir Tim Barrow, the UK’s ambassador to the EU.
Today, therefore, I am writing to give effect to the democratic decision of the people of the United Kingdom. I hereby notify the European Council in accordance with Article 50(2) of the Treaty on European Union of the United Kingdom’s intention to withdraw from the European Union. In addition, in accordance with the same Article 50(2) as applied by Article 106a of the Treaty Establishing the European Atomic Energy Community, I hereby notify the European Council of the United Kingdom’s intention to withdraw from the European Atomic Energy Community.
The letter is 6 pages long and outlines the UK’s approach to negotiations suggesting a number of principles that could be adopted in an attempt to ensure that the negotiations proceed as smoothly as possible:
- We should engage with one another constructively and respectfully, in a spirit of sincere cooperation
- We should always put our citizens first
- We should work towards securing a comprehensive agreement
- We should work together to minimise disruption and give as much certainty as possible
- We must pay attention to the UK’s unique relationship with the Republic of Ireland and the importance of the peace process in Northern Ireland
- We should begin technical talks on detailed policy areas as soon as possible, but we should prioritise the biggest challenges
- We should continue to work together to advance and protect our shared European values
The letter also mentions a White Paper will be released tomorrow (30 March 2017) which will provide details of legislation to repeal the European Communities Act 1972 which gives effect to EU law in the UK. (This legislation is also known as the Great Repeal Bill.)
Theresa May gave a statement on the letter in Parliament details of which can be found at
Donald Tusk responded to the notification letter and mentioned
So, here it is, six pages: the notification from Prime Minister Theresa May, triggering Article 50 and formally starting the
negotiations of the United Kingdom’s withdrawal from the European Union. There is no reason to pretend that this is a happy
day, neither in Brussels, nor in London. After all, most Europeans, including almost half the British voters wish that we would stay together, not drift apart. As for me I will not pretend that I am happy today.
On Friday I will share a proposal of the negotiating guidelines with the Member States, to be adopted by the European Council on 29 April.

A Statement by the European Council (Art. 50) on the UK notification was also issued.
For the European Union, the first step will now be the adoption of guidelines for the negotiations by the European Council. These
guidelines will set out the overall positions and principles in light of which the Union, represented by the European Commission,
will negotiate with the United Kingdom.
In these negotiations the Union will act as one and preserve its interests. Our first priority will be to minimise the uncertainty
caused by the decision of the United Kingdom for our citizens, businesses and Member States. Therefore, we will start by
focusing on all key arrangements for an orderly withdrawal.
We will approach these talks constructively and strive to find an agreement. In the future, we hope to have the United Kingdom as
a close partner.
President Tusk has convened the European Council on 29 April 2017.

What happens next ?
The withdrawal agreement must be negotiated in accordance with Article 218 (3) of the Treaty on the Functioning of the European Union.
An extraordinary European Council will be convened by the President of the European Council, Donald Tusk. (This will happen on 29 April).
The European Council will adopt by consensus a set of guidelines on the orderly withdrawal of the United Kingdom from the European Union. These guidelines will define the overall principles that the EU will pursue during the negotiations based on the common interest of the European Union and of its Member States.
After the adoption of the guidelines, the Commission will very quickly present to the Council a recommendation to open the negotiations. This will be agreed by the College of Commissioners, 4 days after the meeting of the European Council.
The Council will then need to authorise the start of the negotiations by adopting a set of negotiating directives. They must be adopted by strong qualified majority (72% of the 27 Member States, i.e. 20 Member States representing 65% of the population of the EU27).
Once these directives are adopted, the Union negotiator, as designated by the Council, is mandated to begin negotiations with the withdrawing Member State.
