As Andy Burnham gears up to assume the role of Prime Minister, discussions surrounding Britain’s defence budget are intensifying. Downing Street officials are reportedly keen to persuade Burnham to consider the revival of “war bonds” to bolster military funding, aiming for a more substantial investment than the projected £13.5 billion outlined in the Defence Investment Plan (DIP).

Calls for Increased Defence Investment

Senior advisers from Downing Street are preparing to lobby Burnham during upcoming discussions on his priorities as he takes office. The move comes as military leaders and various government factions express increasing concern over the UK’s dwindling defence capabilities. In light of these pressures, there is a push for the Treasury to allow additional borrowing specifically aimed at enhancing military expenditure.

While Burnham is poised to step into a situation where the DIP has already been approved, he is expected to face significant demands from both military officials and government insiders for a reassessment of defence allocations. The urgency of these discussions is underscored by recent comments from Air Chief Marshal Sir Richard Knighton, who emphasised the necessity for the UK to maintain a formidable armed force capable of deterring potential adversaries, including Russia.

Transitioning Leadership and Defence Policies

In a recent statement, Labour Leader Keir Starmer affirmed his intention to announce the DIP ahead of the NATO summit in Ankara on 7-8 July, despite his imminent departure from office. Starmer’s commitment to this significant spending plan has drawn criticism from some Labour MPs, who believe it would have been prudent to leave this decision to Burnham, who has indicated a desire to secure more than the initial £13.5 billion proposed for the Ministry of Defence (MoD).

The political landscape surrounding defence spending is shifting, and Burnham’s allies suggest that if the funding debate is settled by the time he takes office—potentially with additional financial resources identified—he may choose to proceed without further contest. However, should unresolved issues persist, particularly regarding mismanaged programmes, Burnham’s team is prepared to revisit the DIP.

The Proposal for War Bonds

According to sources, Downing Street is exploring the concept of issuing war bonds as a means to finance increased defence expenditure. This idea, initially proposed by former chief of staff Morgan McSweeney before his departure, faced resistance from the Treasury due to concerns over the implications of higher borrowing. Nevertheless, No 10 officials believe that the issuance of bonds could potentially raise up to £20 billion, specifically earmarked for defence spending and exempt from inheritance tax.

Advocates of war bonds assert that this approach would allow the government to offer lower interest rates, thus reducing overall borrowing costs. Additionally, it could stimulate interest among domestic investors, an area that has waned in recent years as hedge funds have become predominant players in the credit market.

Broader Defence Initiatives Under Discussion

In tandem with the war bonds initiative, some Labour MPs are advocating for UK participation in the Defence Security and Resilience Bank, led by Canada. This initiative, which aims to support small defence companies, was previously opposed by the Treasury. Proponents argue that a UK investment of £900 million could unlock access to a lending capacity of €100 billion (£86 billion), significantly enhancing the nation’s industrial output in the defence sector.

As discussions continue, Chancellor Rachel Reeves has indicated ongoing dialogues with Canada and efforts to establish a multilateral defence financing mechanism in collaboration with Finland and the Netherlands. This initiative aims to create a sustainable financial framework to support the UK’s defence needs.

Why it Matters

The ongoing debates surrounding the UK’s defence budget are not merely fiscal; they are critical to the nation’s security posture in an increasingly volatile global landscape. With rising tensions and evolving threats, the decisions made in the coming weeks will have profound implications for the UK’s military capabilities and its role on the world stage. As Burnham prepares for his leadership transition, the resolution of these funding issues will be pivotal in shaping the future of British defence policy.
