Healey's resignation creates benchmark for successor's defence spending deal

John Healey resigned as Defence Secretary on 16 June 2026 over Treasury plans to cap defence spending at 2.68% of GDP, far below the 5% target he had publicly championed. Cabinet ministers rarely quit over spending disputes rather than scandals; such resignations create durable political benchmarks. Healey has now set one in Hansard, making it harder for his successor to quietly abandon Labour's 5% commitment without visible political cost.
