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 will soon begin between the EU and UK. The first formal meeting between the UK and EU negotiators is likely to take place in June.
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.
During these negotiations, the European Commission's aim will be to ensure a maximum level of transparency.
The Commission's approach to transparency
The Article 50 negotiations with the United Kingdom are unique and differ from any other negotiation conducted by the European Union to date. Given their unprecedented nature, the European Commission has decided to adopt a tailor-made approach to transparency.
Meetings held by Michel Barnier, Chief Negotiator for the EU, are published online.
