France's President Emmanuel Macron, the UK's Prime Minister Keir Starmer, Italian Premier Giorgia Meloni and Polish PM Donald Tusk met in Berlin on Wednesday for an E5 summit hosted by German Chancellor Friedrich Merz.
The E5 format was launched in 2024 to bring together the defence ministers of Europe's largest military powers and biggest defence spenders, coordinating support for Ukraine, addressing the US's gradual withdrawal from Europe, and setting up joint defence projects.
