In today’s newsletter: As Zelenskyy urges the EU to step up, divisions remain on how to secure the continent’s future amid Russian aggression

Good morning. Yesterday, Volodymyr Zelenskyy addressed a European Council summit in Brussels, and emphasised the urgency of the EU’s role in Ukraine’s future as Donald Trump turns away. “It’s crucial that our partners’ support for Ukraine doesn’t decrease but instead continues and grows,” he said. And he added: “Europe must always be at the table in discussions about its own security.”

EU countries certainly agree on that, and said yesterday that they were ready to again increase sanctions against Russia – but they are sharply divided on how to achieve it. Meanwhile, after a meeting with western military planners near London, Keir Starmer yesterday appeared to step back from his pledge to put boots on the ground in Ukraine, saying instead that allied forces would be deployed by sea and air in support of Kyiv’s own forces.
