The changing international environment creates a new opportunity for the relationship  between Britain and the EU. From security and defence to trade, migration, and climate,  partnership between the UK and the EU is a strategic imperative. A plurality of Brits and  Europeans believe in a closer UK-EU partnership and want them to come together to  respond jointly to the existential threats of our time. The outcome of the Summit, which took  place on 19 May 2025, was a major step in this direction, laying the groundwork for more  meaningful and stronger relations between Brussels and London. 

In this context, the British Embassy in Sofia, in partnership with the Sofia office of the  European Council on Foreign Relations (ECFR), and the Danish Presidency of the EU, is  organising a high-level conference to discuss the elements of UK-EU strategic cooperation  and Bulgaria’s role in this evolving partnership. The discussions will focus on the new  security environment, the urgency of boosting Europe’s defence capabilities, joint solutions  to irregular migration and broader national security issues, and the need to deepen trade  and economic relations.
