The reason why EU flags were prominently seen at the Last Night of the Proms in 2025 is mainly due to a campaign and sentiment encouraged by pro-EU and anti-Brexit groups. These groups, including "Thank EU for the Music," have distributed thousands of EU flags to concert attendees to show solidarity and support for a borderless music industry across Europe, opposing the Brexit- related difficulties faced by musicians touring in the EU. The prominence of EU flags at the event is a deliberate and symbolic expression of hope for closer UK-EU relations and overcoming the challenges that Brexit has caused in the cultural and music sectors. This took place amid calls to drown out divisive politics and emphasize unity and solidarity, and the EU flags in fact outnumbered Union Jacks at the event, highlighted by media and advocacy groups alike. This display has been a tradition for several years post-Brexit as a form of political and cultural statement at the Proms.
