UK Prime Minister Keir Starmer arrived in Washington on 18 Aug 2025 and entered the White House in the afternoon for talks with U.S. President Donald Trump and Ukrainian President Volodymyr Zelenskyy. Starmer joins a wider group of European figures gathering in the U.S. capital. NATO Secretary General Mark Rutte, European Commission President Ursula von der Leyen and Finnish President Alexander Stubb were earlier seen at the Ukrainian Embassy before heading to the presidential residence. The leaders are assembling for a summit that brings together the United States, Ukraine and key European partners. Specific agenda details have not yet been released, but the high-level attendance underscores the significance of the forthcoming discussions.
