European leaders thank UK's Keir Starmer for Ukraine support upon resignation

British Prime Minister Keir Starmer's unexpected resignation on Monday, June 24, 2026, has prompted reactions from European leaders who lauded his contributions to European security and support for Ukraine. While Starmer may not have been widely popular domestically, his tenure was marked by strong engagement with the European Union and a steadfast commitment to aiding Ukraine in its conflict with Russia.

European Commission President Ursula von der Leyen expressed her gratitude, stating, "European and Ukrainian security is stronger because of you. Thank you, dear Keir." French President Emmanuel Macron also acknowledged Starmer's role in Europe's "coalition of the willing" and his efforts to revitalize EU-UK relations. Ukrainian President Volodymyr Zelenskyy echoed these sentiments on social media platform X, recognizing Starmer as a very active and reliable partner.

Olivia O'Sullivan, director of the UK in the World program at the think tank Chatham House, noted Starmer's work in coordinating European strategy, particularly through the E3 format (Germany, France, and the UK). This framework has been instrumental in shaping European foreign and security policy, especially concerning Ukraine and managing relations with the United States. O'Sullivan suggested that while Starmer's departure might cause a loss of momentum for the E3, the UK's future relationship with the EU and European leaders will largely depend on his successor. Indications point towards former Manchester Mayor Andy Burnham, who is considered broadly pro-European and likely to maintain Starmer's general course on EU and Ukraine policy.
