What Worries the World – June 2026

The findings from our latest research for the Policy Institute at King’s College London and IK in a Changing Europe, show that there is significant public support for a closer relationship between the UK and EU – especially on matters of national security and defence – but as ever public attitudes are complex and Brexit continues to divide opinion. On face value there is openness to greater alignment and rule taking to facilitate a stronger trading relationship but arguments about sovereignty – especially when it comes to immigration – remain persuasive. What is particularly striking from these findings is the warmth among Labour voters to closer ties – which may become a significant political issue as debates about the Labour leadership continue.
