Fresh off his first official international trip to Kyiv, UK Prime Minister Andy Burnham has announced plans to travel to the United States next month alongside fellow European leaders to press the Trump administration to ramp up defense support for Ukraine, as Kyiv faces critical shortages of key air defense systems ahead of an expected winter surge in Russian attacks on critical infrastructure.
In an exclusive interview with Bloomberg, Burnham confirmed that he intends to join the UN General Assembly gathering in New York this September, adding that while final logistical details of the trip have not been fully locked in, a visit is highly likely. This journey will mark his first official visit to the US since he took office as UK Prime Minister in July.
During his Monday visit to Ukraine, Burnham held high-stakes talks with Ukrainian President Volodymyr Zelensky in Kyiv, and chaired the first gathering of the so-called “coalition of the willing”, a UK-France joint initiative originally launched under previous Prime Minister Keir Starmer. Following the meeting, Burnham made clear his policy priorities for the coming weeks, reaffirming the UK’s unwavering commitment to pressuring Moscow over its illegal full-scale invasion.
In a key new commitment to boost Ukraine’s domestic defense production capacity, the UK has agreed to share technical blueprints for British-manufactured components of the Scalp cruise missile — the French equivalent of the UK’s Storm Shadow long-range cruise missile. The transfer of these blueprints will allow Ukraine to begin producing this advanced long-range weapon within its own borders, strengthening its ability to strike Russian supply lines and military positions deep behind front lines.
Burnham’s visit came amid a sharp escalation of Russian strikes across Ukraine in recent weeks, including a deadly attack on a crowded civilian shopping center that claimed the lives of at least 16 civilians. The UK Prime Minister used the visit to double down on longstanding UK support for Kyiv, reaffirming that backing would hold firm for as long as Ukraine needs it.
A core point of urgency driving the upcoming US lobbying mission is Ukraine’s critical shortage of Patriot air defense interceptor missiles, systems that Kyiv relies almost entirely on US supplies for to shoot down incoming Russian ballistic missiles. Recent high demand for these interceptors, driven in part by conflicts in the Middle East including Iran, has depleted global stockpiles, leaving Ukraine’s populated areas and critical energy infrastructure increasingly vulnerable to Russian attacks ahead of the winter months.
Zelensky has publicly stated that Kyiv aims to secure 300 additional Patriot interceptors before winter, when Russia has a well-documented pattern of launching massed strikes on Ukraine’s energy networks to leave civilians without heat or power during the coldest months of the year. While Burnham told Bloomberg he is “really confident” that the supply gap can be addressed through coordinated diplomacy, he noted that solutions will not come solely from Washington.
“There are other players who could help in the mix who we have influence with,” Burnham said. “It’s probably going to be a solution that involves a lot of layers and a lot of negotiation.”
The push for more Patriot supplies comes as the Trump administration has already backtracked on a earlier proposal to allow Ukraine to produce the Patriot systems domestically. Just three weeks after floating that offer in July, Trump told a cabinet meeting that “We have not agreed to that. We’re talking about it. But it’s a hard thing to give away, that kind of technology. These weapons are incredible. We have to be very careful about letting somebody build them.”
Following the Kyiv meeting of the coalition of the willing, Burnham joined the group’s co-chairs — French President Emmanuel Macron and German Chancellor Friedrich Merz — in releasing a joint statement that prioritized strengthening Ukraine’s air defense capabilities as an “urgent priority”. The leaders also strongly condemned Moscow’s “systemic and escalating strikes against Ukraine’s cities, critical infrastructure and civilians”, and pledged to further tighten pressure on Russia’s war funding by expanding sanctions and cracking down on the shadow fleet of vessels used to evade Western oil price caps.
Ahead of his Ukraine visit, which coincided with the 35th anniversary of Ukraine’s independence from the Soviet Union, Burnham delivered a message of solidarity to the Ukrainian people. “the Ukrainian people should be in no doubt: the UK is behind you today and for as long as it takes,” he said. “I am proud of the contribution our country has made to Ukraine and I want the Ukrainian people to hear it directly from me that our support will not waver. After all, Ukraine’s security is our security.”
He added that the deep friendship between the UK and Ukraine would survive long after Russia’s illegal invasion ends, sending a clear message to the Kremlin: “Russia should be in no doubt of our resolve. We will not back down until there is a just and lasting peace.”
