Sir Keir Starmer’s Defence Decision
Sir Keir Starmer is expected to sign an £18 billion defence budget increase within the next week. Spread over four years, the boost will fund all 62 recommendations of the Ministry of Defence’s strategic review, including the Global Combat Air Programme, new F-35A jets, shipbuilding and expanded munitions stocks.
Political Context and Leadership Challenge
The move comes as Starmer’s premiership faces a potential challenge from Greater Manchester Mayor Andy Burnham, cleared by Labour’s National Executive Committee to contest the Makerfield by-election on 18 June. A win would let Burnham launch a leadership contest, heightening pressure on Starmer.
Key Figures Steering the Proposal
National security adviser Jonathan Powell warned that without a substantial boost the armed forces could not afford jets, munitions and technology. Cabinet secretary Dame Antonia Romeo and defence secretary John Healey also backed the £18 billion level, saying lower sums would be insufficient. Chancellor Rachel Reeves had earlier suggested a £10 billion increase.
Funding Figures, Targets and Scope
Britain spends 2.4 % of GDP on defence, targets 2.5 % by April 2027 and 3 % in the next parliament. The £18 billion package, spread over four years, faces a reported £28 billion shortfall in the MoD budget. NATO data rank the UK 12th in proportional spending, down from third in 2021.
Official Statements & Responses
A government spokesperson said the plan will deliver the best kit and technology to frontline forces while supporting the economy, and that officials are finalising it for publication. Powell’s briefing noted allies are increasing defence outlays and the UK has slipped in NATO’s league tables, underscoring the need for a larger budget. Mayor Andy Burnham argued the pressure on defence spending could justify an exception to fiscal rules.
Criticism & Opposition
Treasury officials doubt the affordability of the £18 billion boost, noting a £28 billion deficit. Critics argue the increase is insufficient to meet the 3 % GDP target. Reform UK leader Nigel Farage pledged to disrupt Burnham’s by-election bid, while a senior military source warned that without adequate funding morale could suffer.
Conflicting Reports & Gaps
Sources differ on funding: a Treasury source called the £18 billion plan “fully affordable”, while a Whitehall source called it a “big win” but stressed the need to deliver the money. Rachel Reeves had earlier floated a £10 billion increase, and a £12 billion option was reported.
