Chancellor of the Exchequer Rachel Reeves has reportedly opted for a strategy of departmental budget reductions to finance an increase in the UK's defence spending. This approach involves asking Whitehall departments to trim approximately 1% from their capital budgets, which were meticulously negotiated less than a year ago. The move aims to contribute to a £13.5 billion uplift for the Ministry of Defence (MoD) over a four-year period.
The decision follows a demand from the MoD for an additional £18.5 billion over four years to support its investment plan. While the Treasury has committed £13.5 billion, including £3.5 billion from its departmental reserve, this figure fell short of the MoD's request. This shortfall is understood to have prompted the resignation of Defence Secretary John Healey, who reportedly viewed the allocation as insufficient.
This internal tension highlights a broader challenge for the Labour leadership concerning how to fund rising defence commitments, particularly Keir Starmer's vocal pledge to increase defence spending to 3% of GDP during the next parliament and to 3.5% by 2035. The principal options for financing such an increase — significant spending cuts, tax rises, or increased borrowing — have reportedly been met with political reluctance from the Labour leader.
Treasury insiders, defending the cautious stance, have pointed to historical issues with MoD spending and downplayed some of the stark warnings from military chiefs, suggesting an inherent bias towards higher expenditure. They argue that the £13.5 billion settlement is only around £1 billion per year less than the MoD's demand, a sum they consider modest for a resignation. However, Mr Healey’s departure underscores the depth of concern within parts of the government regarding the adequacy of defence funding in a more volatile global landscape.
The choice to implement departmental 'salami slicing' sits uncomfortably with broader government promises concerning public services, such as addressing crumbling hospitals and overcrowded schools, and the Chancellor's ambitions for economic growth through green energy investment. The long-term implications of Starmer's defence spending pledges could necessitate a fundamental shift in public spending priorities, potentially reversing the post-Cold War 'peace dividend' that helped fund the welfare state. However, with little political appetite for further tax rises and existing concerns about the UK's borrowing costs, the Treasury has reportedly deferred any firm decisions on how to meet the most substantial future defence commitments.
