LONDON, Sept. 21 – British Prime Minister Andy Burnham is heading to New York for the United Nations General Assembly, where he is expected to meet U.S. President Donald Trump for the first time and begin testing a foreign policy approach built around practical cooperation rather than political alignment.
The trip is Burnham’s first major appearance on the international diplomatic stage since becoming prime minister in July. A former mayor of Greater Manchester, Burnham entered Downing Street with considerably less experience in foreign affairs than some of his predecessors, making the UN gathering an important early test of how he intends to represent British interests abroad.
The meeting with Trump is expected on Tuesday, when the U.S. president is scheduled to hold a series of talks with foreign leaders during the UN General Assembly. The discussions come as the United States and its allies face overlapping challenges involving Ukraine, the Middle East, defense spending, artificial intelligence and the future of international cooperation.
Burnham has made clear that he does not intend to avoid disagreements with Washington when he believes British interests require a different position. At the same time, he has stressed that his instinct is to work with other leaders and look for areas where cooperation remains possible.
That approach marks a change in tone from his predecessor, Keir Starmer, who invested considerable political effort in building a close relationship with Trump. Burnham is instead seeking to demonstrate that maintaining the UK-U.S. relationship does not necessarily mean accepting the American administration’s position on every issue.
The British prime minister has described his approach as pragmatic, with his government emphasizing decisions based on what it considers to be Britain’s national interests.
The issue of Ukraine is expected to be among the most important subjects during Burnham’s discussions in New York. Britain has continued to push for additional military support for Kyiv, particularly air defense capabilities needed to protect Ukrainian cities and infrastructure from Russian attacks.
Burnham visited Kyiv last month and called for greater international support for Ukraine. His government has subsequently continued efforts to strengthen Ukraine’s air defenses. The British government announced on Sept. 8 that it would provide a £100 million package including Patriot missiles, alongside other defensive equipment.
The United Kingdom has also been working with NATO allies on broader efforts to strengthen Ukraine’s military position while diplomatic discussions continue over a possible ceasefire.
Burnham looks for common ground with Trump
The relationship between Burnham and Trump has already had an initial period of contact. The two leaders spoke by telephone shortly after Burnham entered office on July 20, with Downing Street describing their conversation as constructive. They spoke again on Sept. 7, discussing Ukraine, the Middle East and economic issues.
According to the British government, Burnham and Trump agreed during their September call on the need to continue working toward a ceasefire in Ukraine that would prevent further loss of life. Burnham also reiterated Britain’s support for U.S.-led diplomatic efforts.
The two leaders have therefore already established a line of communication before meeting in person.
Kim Darroch, who previously served as Britain’s ambassador to the United States, told Sky News that Trump would likely want the encounter to proceed smoothly. Darroch also pointed to the importance of personal chemistry in Trump’s dealings with foreign leaders, while acknowledging that uncertainty would remain around the meeting.
That personal relationship could matter as Burnham seeks to protect cooperation between London and Washington on defense and security while pursuing British positions that do not always coincide with those of the White House.
One example is Britain’s position on Israeli settlements in the occupied West Bank. The British government joined a group of countries backing restrictions on imports from Israeli settlements, presenting the move as an expression of Britain’s position on international law and its broader foreign policy principles.
Burnham has argued that Britain needs to be clear about what it stands for, even when doing so could create differences with close allies. The position has added another layer to the challenge facing him as he prepares to deal directly with Trump.
At the same time, Burnham has shown an interest in maintaining areas of cooperation with Washington. His government is particularly focused on defense, security and emerging technologies, areas where Britain and the United States have longstanding links.
Burnham’s meetings in New York are also expected to include discussions about artificial intelligence and international security. Britain has sought a larger role in the development and regulation of AI while maintaining close technological cooperation with the United States.
The prime minister’s government is also preparing to announce further cooperation with Washington in defense-related artificial intelligence, reflecting the wider effort to keep the bilateral relationship focused on practical areas of shared interest.
Another potential area of cooperation is security in the Arctic and North Atlantic. Burnham spoke with Danish Prime Minister Mette Frederiksen on Sunday ahead of their respective visits to New York. According to Downing Street, the two discussed a forthcoming agreement involving the United States, Greenland and Denmark aimed at strengthening security in the region.
The conversation also covered Ukraine, with Burnham saying he hoped to make further progress with international partners on increasing support for Kyiv during the UN General Assembly.
The British prime minister’s relationship with Canadian Prime Minister Mark Carney could also become relevant as governments seek ways to protect their interests amid growing competition among major powers. Carney has promoted greater cooperation among middle powers, including countries that do not have the scale of the United States or China but have significant economic and diplomatic influence.
Burnham and Carney have developed a visible personal connection, including attending an Everton football match together last week. Their governments have also shared concerns about how smaller and middle-sized economies can respond to a changing international system.
Defense spending puts pressure on Burnham at home
While Burnham will be focused on diplomacy in New York, his government’s defense policy remains closely tied to his discussions with Washington.
The United States has continued to press NATO members to take greater responsibility for the alliance’s defense. Burnham has said Britain needs to increase defense spending and strengthen domestic defense production, including investment that could create jobs within the UK.
The details of that spending strategy, however, remain a significant issue for the government.
Finance Minister John Healey is due to present the government’s budget on Oct. 28. Among the challenges facing ministers is how to address a funding gap in Britain’s defense investment plans while balancing defense commitments against spending pressures in areas such as social security and public services.
Burnham has acknowledged the tension between those priorities. Earlier this month, he said the government would do everything necessary to protect national security but argued that security policy could not be separated from the economic and social needs of people in Britain.
That balance is likely to be closely watched in Washington, particularly as the Trump administration urges European allies to assume a larger share of NATO’s collective defense burden.
For Burnham, the UN visit therefore carries significance beyond a single meeting with Trump. It is an opportunity to establish how Britain will conduct itself under his leadership at a time when relations between the United States and many traditional allies are being reshaped.
His stated approach is to preserve cooperation where interests overlap, while maintaining the freedom to disagree when British priorities demand it.
The Trump meeting will provide an early indication of how that strategy works in practice. It will also give Burnham a chance to establish a direct relationship with the U.S. president while addressing issues that stretch well beyond the bilateral relationship, from Ukraine and Middle East security to defense, trade and artificial intelligence.
