John Healey resigned as UK Defence Secretary after the Treasury blocked his proposal to join the Defence, Security and Resilience Bank (DSRB), a multinational investment vehicle. The move leaves new Defence Secretary Dan Jarvis facing severe budget constraints, with former national security adviser Lord Mark Sedwill warning that Royal Navy ships may need to be mothballed. Healey's resignation letter to Prime Minister Sir Keir Starmer highlighted a lack of ambition to bridge the gap between defence commitments and available resources, according to the report.

The £870 million membership fee that sparked a resignation

Healey had championed the UK's membership in the DSRB, an international bank promoted by Mark Carney that would provide low-cost funding for NATO allies . the Treasury, under Chancellor Rachel Reeves, refused to sign off on the £870 million membership fee, effectively killing the proposal. According to Healey's resignation letter, this dismissal of multilateral funding options demonstrated a lack of ambition to address the widening gap between defence commitments and available resources. The move has intensified pressure on Jarvis to find alternative funding sources.

Lord Sedwill's warning: a navy with mothballed ships

Former national security adviser Lord Mark Sedwill has asserted that the government must spend more money on defence, warning that without significant increases, Jarvis would be forced into ruthless prioritisation and sweeping cuts across all services. As the report states, Sedwill suggested that some Royal Navy ships might need to be mothballed if they are not ready for deployment, underscoring the operational risks of underfunding. He also criticised the Ministry of Defence as too top-heavy and bureaucratic , calling for structural reforms to improve efficiency.

Gordon Brown's quiet role and the Treasury's veto

The controversy extends beyond domestic politics, revealing behind-the-scenes diplomatic efforts involving Canada and former Prime Minister Gordon Brown. Canada's High Commissioner to the UK, Bill Blair, confirmed that Brown had held direct talks with Carney about UK membership in the DSRB. Blair described ongoing discussions between bank officials and the UK Ministry of Defence and Treasury as very encouraging, though the Treasury's opposition has cast doubt on whether these will proceed. The source notes that Brown was brought in by Starmer to adviise the government.

A 0.08% real-terms increase vs. £322.6 billion in welfare

Starmer has yet to set a clear timetable for raising defence spending to the NATO target of 3% of GDP by 2030. According to the report, his recent offer to Healey amounted to a negligible real-terms increase of just 0.08%, which Healey deemed inadequate for national security. In contrast, the government has allocated £322.6 billion to welfare spending—nearly a quarter of total government expenditure—while defence budgets have been cut in real terms over many years. This disparity raises questions about the government's priorities amid growing global threats.

Can Dan Jarvis avoid the same fate?

Jarvis's early performance has drawn criticism; he failed to appear for his first 24 hours in post and was ridiculed for publicly backing Starmer's defence plan without having read it. This lack of preparedness, combined with the Treasury's resistance to reallocating funds from welfare or net-zero initiatives, suggests that the new Defence Secretary will have limited room for manoeuvre. The postponement of the long-awaited Defence Investment Plan—over a year since the Strategic Defence Review—further highlights the government's indecision. The open question remains whether Jarvis will push for multilateral funding mechanisms like the DSRB or accept the Treasury's constraints.
