Prime Minister Andy Burnham is facing mounting pressure within his own Labour Party over the government's defence spending plans, particularly regarding the commitment to allocate 3 percent of GDP to defence by 2030. At Prime Minister’s Questions, Burnham declined to guarantee that the 3 percent target would be included in next year’s Spending Review, prompting criticism from senior Labour figures and opposition members alike.
Tan Dhesi, Labour chairman of the Commons Defence Committee, urged the Prime Minister not to “kick the can down the road” and emphasized the need for an urgent, clear pathway to meet the 3 percent threshold. Dhesi cited increased threats from Russia and shifting priorities within the United States, which he said had deprioritized European security, as reasons for immediate defence investment. He warned that relying on vague assurances or “vibes alone” would not suffice to ensure national security.
Burnham reaffirmed Labour's commitment to fully fund the defence investment plan and pledged to meet NATO's higher target of 3.5 percent of GDP on defence spending by 2035. However, he notably avoided committing to the closer 2030 target, which the current plans project defence spending to reach only 2.7 percent by that year. The Chancellor, John Healey, who resigned as defence secretary in June over similar concerns, will not address the 2030 goal in this October’s Budget; instead, officials plan to outline a funding trajectory in the 2027 Spending Review.
The absence of a clear 2030 timeline has drawn criticism from former Labour defence secretary Lord Hutton of Furness, who said delaying firm commitments risks leaving the UK vulnerable to Russian aggression. Hutton stressed that President Vladimir Putin might act imminently, regardless of the UK's financial planning schedule.
Opposition Conservatives also challenged Burnham’s approach. Kemi Badenoch questioned whether the Prime Minister’s assurances were sufficient to protect the nation, urging a more serious commitment. Burnham responded by reiterating Labour’s intention to build Britain’s resilience and to fully support the defence investment plan.
The heightened concerns come amid increased intelligence warnings about Russia’s grey-zone tactics—actions short of outright military assault—that have escalated tensions across Europe. Recent incidents include Germany attributing a foiled drone attack on Leipzig/Halle airport in August to Russia, and Russian threats directed at British factories following the UK’s assistance to Ukraine in building Storm Shadow missiles.
The debate over defence spending has also sparked internal dissent, exemplified by Labour MP Diane Abbott’s remarks disputing the reality of the Russian threat, which drew sharp rebuke from Conservative critics, including a former Army officer who accused her of undermining UK security.
As security challenges evolve, the UK government faces growing calls from across the political spectrum to clarify and accelerate its defence funding commitments to address an increasingly complex international environment.
