Negotiation mandate

Article 50 of the Treaty on European Union sets out the procedure for a Member State to withdraw from the European Union. Following the UK's notification of its intention to leave the EU, negotiations began on 19 June 2017. The EU and UK negotiators agreed on the "Terms of Reference for the Article 50 TEU negotiations" which stipulates the structure of the negotiations, dates and priorities for future negotiating rounds.

In the meantime, the UK remains a full member of the EU. This means that all existing EU rights and obligations continue to apply to the UK.
