Faced with the war in Ukraine and the attitude of the Trump administration, European defence is now a top priority for the EU. At the same time, security is a central theme of the British government’s ‘reset’ with Brussels. As the EU argues internally about how to structure its defence procurement and we approach a potentially crucial EU-UK summit on May 19, speakers will discuss how the EU can best work with the UK and other non-EU states (e.g. Norway, Canada, Ukraine itself) for a more coherent, effective and self-sufficient European defence. And what is in fact likely to happen, at the May summit and beyond.
