EU enlargement is back at the top of the EU’s political agenda as Russia’s war against Ukraine has transformed it from a bureaucratic process into a matter of European security.

In this episode, Mark Leonard speaks with Lykke Friis, co-chair of ECFR’s council, director of the Danish think-tank Europa, and former Danish minister, as European leaders gather for the European Political Community summit in Copenhagen. Together they discuss why Denmark has shifted to advocating for enlargement and why Europe’s future security may depend on bringing Ukraine and Moldova closer.

Is the EU ready for a new wave of member countries? Can enlargement be both geopolitical and merit-based? And what role will Denmark play in defining the EU’s next chapter?
