Defence Spending Must Be Tamed for a Progressive Future

Chancellorship and the Weight of Responsibility

When Andy Burnham made his appointment of John Healey as chancellor, it was clear that the new prime minister had taken a decisive step toward stabilizing the country's economic direction. The weeks of speculation between potential candidates—Ed Miliband and Shabana Mahmood—highlighted just how much the Labour government needed a steady hand in the Treasury. That Healey, with his experience as defence secretary, was chosen signals an understanding that the new government must balance its military ambitions with its social priorities.

Healey's two years in defence meant that he would know both sides of the argument when it came to one of the biggest questions of the forthcoming budget: how to meet the bold new NATO defence spending targets without derailing the social ambitions of the Burnham government.

The political choice here was not just about personnel—it was about priorities. The MoD's track record speaks for itself: a long history of overspending that is only matched by its constant claims of underfunding. It's a paradox that has plagued public accountability and budgetary planning for years. But now, with the appointment of a seasoned fiscal operator like Healey, there's an opportunity to bring clarity and control.

Defence Spending: A Complex Equation

There's no denying that defence spending is one of the most challenging aspects of public finance. The Ministry of Defence has always been a black hole in terms of financial reporting, with a culture of secrecy and a tendency to overspend when under pressure. When I was a special adviser during the Gordon Brown years, we often joked that if you wanted to know what was going on in procurement, just talk to BAE Systems—this was a sardonic way of acknowledging the extent of producer capture by UK defence firms.

Today, those same problems persist, though they've been given new language: sovereign capability, GDP percentages, and grand strategic visions. But underneath all these terms lies the same hunger for resources that the MoD has always displayed. As John McTernan notes, it's like a Cyclops—hungry, powerful, and insatiable.

The Role of Leadership in Reform

It's one thing to recognize the problem, but quite another to fix it. That's where leadership comes in. We've seen this in other sectors where reform was needed. For instance, the NHS under Wes Streeting has shown signs of control over spending after years of unchecked growth. The Institute for Fiscal Studies recently reported that for the first time since 2013-14, the NHS received no additional funding from the Treasury reserve or capital budgets.

This is not to say that the MoD should be starved of resources, but rather that its spending must be aligned with national priorities. That means being more accountable and transparent in how those resources are spent, and ensuring they're used for genuine security needs rather than political ones.

Global Context and Geopolitical Challenges

The current geopolitical landscape adds another layer of complexity to the issue. The recent Hague Summit brought increased attention to NATO defence spending commitments, with many nations pledging to increase their military investment. But as McTernan correctly points out, this is not simply a matter of matching military budgets—it's about how that money fits into the broader picture of social and economic progress.

The United States, under Trump's leadership, has been pushing for greater contributions from its allies. However, there are alternatives to this approach. Canada's Prime Minister Mark Carney has demonstrated a more balanced stance, one that recognizes the need for strong alliances while also asserting national sovereignty. His willingness to challenge American trade practices and explore deeper ties with the EU offers a model for the UK.

Labour's Vision and the Need for Balance

The Burnham government is taking on a significant challenge: how to build a socially democratic Britain that invests in its people while also maintaining a credible defence posture. His promise of growth in every postcode, his focus on devolution, and his commitment to housing and social care show a clear direction for national development.

This approach means that the MoD cannot be treated as an isolated department but must be integrated into the larger fabric of progressive governance. It's not about cutting defence spending; it's about making sure those funds are used wisely, with accountability and transparency at the core of every decision.

Political Opportunity in the Deficit

Defence can be a powerful wedge issue for Labour, especially when compared to the political extremes. The Conservative Party and Reform UK have shown little regard for national interest, willing to align with Trump's agenda even at the cost of British sovereignty. On the left, the SNP and Greens struggle with their own definitions of national security.

In this context, Labour has a chance to articulate what a responsible, progressive approach to defence looks like. By treating it not as an end in itself but as a tool for protecting the values that matter most—social justice, equality, and national cohesion—Labour can redefine how Britain engages with the world while serving its own people.

A New Path Forward

Ultimately, this moment calls for a reimagining of what it means to be a modern state. The Ministry of Defence must be part of a broader strategy that values both national security and social investment. With Healey's leadership, we have the opportunity to build a system where defence spending is not only sustainable but also purposeful.

The future of Britain will depend on its ability to balance its past with its present needs. And at the heart of that balance lies a disciplined, responsible approach to how we spend our money—especially when it comes to matters of national security. As we move forward, let's make sure that the Ministry of Defence is not just another department, but a cornerstone of a progressive society.
