Their Delegation is one of 143 EU diplomatic missions around the world. They were established following the UK’s withdrawal from the EU on 1 February 2020 to represent the EU and engage with the UK government, political actors, media, academia, business and the British public. 

The core mission of the EU Delegation to the UK is to build and strengthen the new EU-UK relationship post-Brexit. The United Kingdom is an important strategic and economic partner for the EU, with significant people-to-people links and shared values. It is the EU's third-largest trading partner after the US and China and has a population of almost 5 million EU citizens who live, work and study across the country.
