Burnham’s Ukraine policy: a test of the balance between domestic delivery and international leadership

Britain’s commitment to Ukraine is entering a new phase. On 8th September, the Government announced a £100 million package of air-defence support, including Patriot missiles, alongside tens of thousands of long-range artillery rounds and an acceleration of its programme to supply more than 120,000 drones to Ukraine this year. The package, intended in part to strengthen Ukraine’s defences ahead of the winter, demonstrates that the Government’s promise to stand “shoulder to shoulder” with Kyiv is translating into increasingly substantial military commitments.

The Prime Minister’s visit to Kyiv on 24th August suggested his support for Ukraine extends beyond the symbolic continuity established during Volodymyr Zelenskyy’s visit to Portsmouth in late July. Burnham choosing Ukraine for his first overseas trip as PM was itself a significant political signal, but the substance of the visit went further. During meetings with Zelenskyy and other international partners, Burnham announced that the UK would permit the sharing of classified technical information relating to British components used in the SCALP/Storm Shadow missile programme, supporting efforts to establish domestic missile production capacity in Ukraine.

These developments build on the direction established in Portsmouth. The Stone Cloak agreement was designed to deepen technological cooperation by enabling Ukraine to benefit from British electronic warfare capabilities; the Kyiv announcement takes that logic further, placing greater emphasis on joint production and Ukraine’s sovereign defence-industrial capacity. Burnham also chaired a meeting of the Coalition of the Willing, underlining the UK’s ambition to retain a leadership role among Ukraine’s international partners.

There is, however, an important strategic implication. By moving from providing equipment towards sharing technology, intellectual property and production expertise, Britain is further entrenching itself in Ukraine’s long-term defence architecture. That may prove strategically valuable for both countries, but it also raises the stakes of Burnham’s commitment to defence spending. Russia responded angrily, saying it could retaliate against the UK by striking military targets inside and outside Ukraine. Burnham nevertheless insisted that British support would continue despite what he described as “outrageous” Russian threats.

The challenge is whether this willingness to make difficult strategic commitments abroad will be matched by difficult fiscal decisions at home. Burnham’s choice of Chancellor, former Defence Secretary John Healey, initially instilled optimism in the defence sector that his government would take defence spending and national security seriously. Healey previously resigned under Keir Starmer’s government over his inability to commit to spending 3% of GDP on defence by 2030. Yet optimism is quickly turning to dismay following the announcement that the roadmap to hitting this target will be deferred until next year’s Spending Review.

Being a better communicator than Starmer does not change the material reality he faces; Britain spends more servicing the interest on its debt than on its defence capabilities. As impatience grows in the defence community and the flaws of the Defence Investment Plan continue to be scrutinised, maintaining Britain’s leadership role in supporting Ukraine will depend on whether the government is willing to make difficult fiscal and political choices. Andy Burnham indicating at PMQs this week that he wouldn’t cut welfare to fund defence suggest he’s trying to have it both ways, without risking getting off-side with Labour backbenchers.

Where Keir Starmer was often criticised for focusing too heavily on foreign relations, Burnham’s premiership has so far seen a renewed drive on domestic issues. Starmer’s argument that events abroad were inextricably connected to Britain’s domestic condition eventually wore thin with a public that saw it as a cover for the government’s failure to deliver change quickly enough.

Burnham's challenge is to succeed where Starmer failed, in this area as much as any other. In his first speech to the House of Commons on 1st  September, the PM claimed that “Britain’s defence starts in Ukraine” and vowed that British support would not waver, “whatever the threats we face”. Beyond the rhetoric, the question is whether he can sustain this commitment when difficult political and fiscal choices begin to bite.

Indeed, the new PM may find it more difficult than Starmer did to argue that his domestic and international agendas are inseparable. Increased defence spending, deeper commitments to Ukraine and the costs of Britain’s international leadership will compete directly with the promise of radical change on the domestic front, something he’s put central to his premiership. Whether the PM can navigate this whilst sustaining his early boost in popularity will be key to answering the question of whether Labour was right to switch horses this summer.
