UK Prime Minister Andy Burnham is preparing for a planned visit to the United States in September, putting Ukraine support, NATO defence spending and the future of transatlantic security high on the agenda.
The proposed trip comes at an important moment for the UK and its allies. European governments are under increasing pressure to strengthen their military capabilities, while the future level of US support for Ukraine remains a major concern for countries across Europe.
Burnham became UK prime minister on July 20, 2026, succeeding Keir Starmer. The UK government confirms that Burnham is the current holder of the office, while Starmer announced on September 1 that he would also step down as an MP.
The planned American visit is expected to take place around the United Nations General Assembly in New York. Burnham has indicated that he intends to travel to the US and has said European leaders need to make their case to President Donald Trump over Ukraine’s defence requirements. One issue reportedly expected to feature is Ukraine’s need for additional American-made Patriot air-defence missiles.
Ukraine Support at the Centre of the Talks
Ukraine is likely to be one of the most important issues surrounding Burnham’s planned US engagement. European governments remain concerned about ensuring that Ukraine has sufficient military capabilities to defend itself, particularly at a time when the future scale of American assistance remains strategically important.
Burnham has already demonstrated a willingness to make Ukraine a significant part of his early foreign-policy agenda. His recent visit to Kyiv included discussions about Ukraine’s defence needs, with the British leader indicating that he would raise the issue of additional Patriot missile support during his planned US trip.
Patriot systems are among the most capable air-defence systems available to Ukraine. They can help defend population centres and critical infrastructure against missile and other aerial attacks.
European countries have limited stocks of some advanced air-defence equipment, making continued American involvement particularly important. Any agreement that increases access to Patriot interceptors could therefore have wider implications for Ukraine’s ability to protect its cities and infrastructure.
NATO Defence Spending Is Changing
The Ukraine debate is taking place alongside a much larger transformation in NATO’s approach to defence spending.
At the 2025 NATO Summit in The Hague, alliance leaders agreed to a new target requiring members to invest 5% of gross domestic product annually in defence and defence-related security spending by 2035.
The commitment is divided into two main categories.
At least 3.5% of GDP is intended for core defence requirements, including the forces and capabilities needed to meet NATO’s agreed capability targets. Up to another 1.5% can be directed towards defence- and security-related areas such as critical infrastructure, cyber protection, civil preparedness, resilience, innovation and strengthening the defence industrial base.
The decision represents a substantial change from NATO’s previous benchmark of 2% of GDP for defence spending.
It reflects concerns about the security environment in Europe and the need for alliance members to ensure they have sufficient troops, equipment, ammunition, infrastructure and technology to respond to potential threats.
Britain Faces a Difficult Spending Decision
For the UK, meeting the new NATO commitment presents a significant financial challenge. Britain has committed to reaching the alliance’s 3.5% core defence spending target by 2035. However, the government still faces difficult decisions over how quickly it should increase spending and how additional funding can be accommodated within its wider financial plans.
The issue has become more complicated because the UK’s existing Defence Investment Plan faces a funding shortfall. Recent reporting has highlighted pressure on the government to explain how it intends to finance future increases while maintaining its broader fiscal commitments. For Burnham, the challenge is not simply to promise additional defence spending. His government must also determine how that money will translate into actual military capability.
That could include investment in equipment, personnel, ammunition, military infrastructure and emerging technologies.
Washington Wants Greater European Responsibility
The United States remains central to NATO’s military strength, but Washington has increasingly encouraged European allies to assume greater responsibility for their own defence. The new 5% NATO commitment is partly a response to that pressure.
NATO reported in June 2026 that European allies and Canada had been significantly increasing defence expenditure, with their combined spending rising by nearly 20% in real terms during 2025 compared with the previous year. The objective is not simply to increase defence budgets. NATO wants members to develop the military capabilities required to fulfil agreed alliance plans.
That means investment in areas such as air and missile defence, long-range weapons, logistics, large land formations and other capabilities identified in NATO’s updated targets.
Britain Remains a Major NATO Military Power
The UK continues to occupy an important position within the alliance. Britain maintains significant conventional military capabilities and an independent nuclear deterrent. It also contributes to NATO activities and wider European security efforts.
That role gives London considerable influence when NATO countries debate the future of collective defence. Maintaining that position requires sustained investment.
Modern military preparedness increasingly involves technologies and capabilities that go beyond traditional weapons systems. Cyber operations, drones, artificial intelligence, satellites, electronic warfare and advanced air-defence systems are becoming increasingly important to modern defence planning.
NATO’s new spending framework reflects this broader understanding of security by allowing part of the 5% commitment to be used for infrastructure, resilience, innovation and defence-industrial development.
The Political Challenge for Burnham
Increasing defence spending also creates a difficult domestic political calculation for the new British government. More money directed towards defence could potentially mean less room for other government priorities unless ministers can identify additional revenue or make changes elsewhere in public spending.
Burnham’s government is already dealing with pressure over public services, household costs and the wider state of the British economy. Recent financial-market developments have added to those pressures, with borrowing costs rising and the government facing difficult choices over how to fund its policy commitments.
The prime minister must therefore balance Britain’s international obligations with expectations from voters at home.
The UK-US Relationship Remains Crucial
Defence is only one part of Britain’s relationship with the United States. The two countries have long maintained close cooperation in intelligence, military affairs, nuclear security, diplomacy and other strategic areas.
For London, maintaining American engagement with European security remains important. For Washington, Britain represents one of its most significant European military partners.
That relationship means a meeting between Burnham and senior US officials could have consequences beyond the immediate issues being discussed. It could provide an opportunity for Britain to explain its defence plans, discuss Ukraine and reinforce the importance of continued American involvement in European security.
NATO’s Future Is About More Than Money
The debate over NATO spending is increasingly focused on whether countries can convert higher budgets into usable military capabilities. A country can increase its defence expenditure without necessarily becoming significantly more prepared for a major conflict if money is not directed towards the capabilities the alliance needs.
NATO is therefore placing greater emphasis on military readiness, industrial capacity and the ability to sustain forces over time.
The alliance has also been working to expand defence production and improve cooperation between European, Canadian and US defence industries. NATO says its initiatives are intended to increase industrial capacity, particularly in areas such as air defence and strike capabilities.
For Britain, that could create opportunities for its defence industry while also increasing pressure on the government to demonstrate that additional spending produces tangible results.
A Critical Moment for European Security
The proposed Burnham visit comes as European governments reassess their long-term security strategies. Russia’s war against Ukraine has fundamentally changed defence planning across Europe, while concerns about the future level of American involvement have encouraged European countries to increase their own military capabilities.
NATO’s new spending commitment is one of the clearest signs of that shift. For Britain, the situation presents both a challenge and an opportunity. The country has the military capabilities and diplomatic influence to play a major role in European security, but fulfilling that role will require significant long-term investment.
What the September Visit Could Mean
The planned US trip could become one of Burnham’s most important foreign-policy engagements since taking office. If Britain and its European partners succeed in securing stronger American support for Ukraine, the discussions could provide reassurance to Kyiv and other NATO members.
If the US takes a more limited approach, European governments could face greater pressure to provide additional military assistance themselves.
The talks could also offer an indication of how Burnham intends to position Britain within the changing transatlantic relationship. Because the visit is still planned rather than completed, the precise agenda and any formal meeting with Trump could change.
Conclusion
Andy Burnham’s planned September visit to the United States comes at a pivotal moment for Britain, NATO and the wider transatlantic alliance.
Ukraine’s need for continued military assistance, NATO’s new 5% defence investment commitment and the future role of the United States in European security are all contributing to a rapidly changing strategic environment.
For Britain, the challenge is particularly significant. The government has committed to NATO’s 3.5% core defence spending target by 2035, but it must still determine how to finance that increase while addressing competing domestic priorities.
For Washington, the UK’s approach to defence spending and its continued support for Ukraine will be important indicators of Britain’s role as a major European ally.
The planned talks could therefore shape more than Britain’s relationship with the United States. They could also influence the UK’s future position within NATO and the wider debate over how Europe should respond to an increasingly uncertain security environment.
