The 2025 London Summit on Ukraine, formally the Securing Our Future London Summit, was held on March 2, 2025, at Lancaster House and brought together European and allied leaders to strengthen support for Ukraine after the public rupture between Volodymyr Zelenskyy and Donald Trump in Washington. The meeting centered on building a peace framework for Ukraine and presented Europe as more prepared to take the lead if U.S. policy remained uncertain.
British Prime Minister Keir Starmer convened the summit to unify European backing for Ukraine and to draft a peace plan that could later be taken to the United States. The summit’s main outcome was the creation of a Coalition of the Willing, a group of countries prepared to offer long-term security guarantees for Ukraine.
Starmer framed the gathering as a historic turning point, arguing that Europe had to take greater responsibility for the conflict’s resolution. Russia dismissed the summit’s outcome, saying the funding and military pledges would only prolong the war.
Coalition plans
The UK and France led work on a peace plan aimed at securing a ceasefire and what leaders called a “just peace.” Several countries also signaled readiness to join a European-led peacekeeping force, later described as Multinational Force Ukraine, to help enforce any eventual settlement.
The UK announced a £1.6 billion missile deal for 5,000 lightweight multirole missiles. Separately, the EU unveiled its €800 billion ReArm Europe defense investment plan, intended to strengthen European military capacity and support Ukraine over the longer term.
Starmer’s framework
Starmer set out four priorities for the summit: sustain military aid and economic pressure on Russia, ensure Ukraine has a seat at any negotiating table, strengthen Ukraine’s long-term defenses to deter future aggression, and build a coalition capable of guaranteeing and defending any peace deal.
The message was that Europe could not wait for Washington to define the next phase of the war. The summit was designed to show unity, deterrence and a willingness to back diplomacy with hard military and financial commitments.
Who attended
The meeting brought together Zelenskyy, Starmer, Emmanuel Macron, Justin Trudeau and leaders from Germany, Italy, Poland, Spain, the Netherlands and the Nordic states. Senior officials including Ursula von der Leyen, Mark Rutte and Antonio Costa also took part.
The broad attendance gave the summit political weight and reinforced the idea that Ukraine’s future security would depend on sustained coordination across Europe and its allies.
