Starmer Faces Opposition Fire Over Defence Spending as Questions Mount Over Funding

Prime Minister Sir Keir Starmer has fiercely defended his government’s new defence investment plan after facing sharp criticism in Parliament over how it will be funded. The clash, one of his final appearances at Prime Minister’s Questions before stepping down, reflected a leader determined to protect his legacy even as attention increasingly shifts to what comes next.

Opposition leader Kemi Badenoch accused Starmer of leaving behind a £4.7 billion funding gap in the government’s newly announced defence programme, arguing that the financial burden will fall on his expected successor, Andy Burnham. She described the plan as “too little, too late” and questioned whether it had been fully costed. Starmer rejected the criticism, insisting Labour has committed the biggest increase in defence investment for decades and that existing fiscal headroom would allow the spending to be delivered without compromising public finances.

The disagreement comes after the government unveiled a £15 billion defence investment package, including major spending on drones, autonomous weapons and a new “Hybrid Navy.” While ministers say the plan reflects the realities of modern warfare and prepares Britain for future security threats, critics argue that important questions remain about where the remaining money will come from.

Beyond the political exchanges, the debate highlights a broader challenge facing many governments today. With global security threats increasing, defence spending has become harder to avoid. Yet every additional pound committed to the military raises equally difficult questions about what other public projects may have to be delayed or scaled back. In Britain’s case, ministers have already indicated that some transport and infrastructure projects could be reduced to help finance the new strategy.

For Starmer, the defence plan is intended to be one of the defining achievements of his premiership. For his critics, however, it risks becoming an expensive promise that someone else will have to fund. As Britain prepares for a change in leadership, the debate has become less about whether the country needs stronger defence and more about how that ambition should be paid for.
