Just before the government formally presented its Defence Investment Plan, John Healey and his successor Dan Jarvis held a private discussion behind the Speaker’s chair in the House of Commons. Healey, who had previously stepped down as defence secretary due to dissatisfaction with the plan’s financial provisions, observed as Jarvis highlighted an additional £1.5bn secured from the Treasury during his brief tenure. Westminster observers noted the improved collaborative atmosphere between Jarvis and Chancellor Rachel Reeves, a sharp departure from the tension that followed Healey’s resignation.
While this extra funding brought the total commitment for the armed forces to £15bn, Healey remained publicly skeptical that the amount was sufficient. Sir Keir Starmer had previously framed the strategy as a foundational platform for his successor. Even Jarvis conceded during the Commons session that further action would be necessary beyond the current proposal.
Reports from Healey’s allies following his resignation had criticized “Treasury trickery,” suggesting that the reported investment figures were artificially inflated. A closer examination of the plan reveals that while the total commitment stands at £15bn, only £10.3bn has been clearly identified. The remaining £4.7bn remains unfunded, a deficit that must be addressed in the autumn Budget—a responsibility likely falling to Andy Burnham and his chosen chancellor.
Furthermore, the plan relies on securing £10.7bn through “defence efficiencies” by 2030, though details on how these savings will be realized remain thin. The strategy also assumes that defense will be a primary focus in the upcoming spending review, implying potential cuts elsewhere in government. This leaves open questions regarding the priorities of Burnham, should he become prime minister as anticipated.
Although Burnham has held discussions with Healey regarding defense, those close to the prospective leader suggest his specific philosophy on the matter remains largely unknown. In his recent outline for a future Downing Street tenure, defense issues were not a prominent feature. Jarvis confirmed to BBC Newsnight that he had consulted Burnham on the plan, though noted that security restrictions prevented a full briefing and that Burnham did not sign off on the final document. When asked, the defence secretary declined to confirm if Burnham was aware of the £4.7bn shortfall he may inherit.
Opposition during the announcement came not only from the benches opposite but from Labour MPs themselves, with senior figures including defence committee chair Tan Dhesi and treasury committee chair Dame Meg Hillier arguing that the current financial allocation is inadequate. An ally of Burnham characterized the identified gaps as an impending spending pressure. While there may be relief that Starmer finalized the plan before stepping down, it is clear that the contentious issues surrounding defense expenditure will remain a significant challenge for the incoming administration.
