Nato Secretary General Mark Rutte has called on Britain to demonstrate a credible path of annual defence budget increases to meet the alliance's target of spending 3.5% of GDP on defence by the mid-2030s. In an unusually pointed intervention, Rutte stressed that the UK cannot delay significant spending hikes until just before the 2035 deadline.
Why Nato Wants a Credible Path
Rutte, a former Dutch prime minister, argued that reaching the 3.5% target requires steady, yearly increments rather than a last-minute surge. "You need a credible path towards that 3.5%, and yearly increments," he said in an interview with the Press Association. He made similar remarks to the BBC, noting that the UK understands the target cannot be met "in one go in 2034" and must be achieved gradually.
The call comes after the UK signed up to the Nato-wide target in summer 2025, under pressure from US President Donald Trump. The commitment equates to nearly £30bn more in military spending by the middle of the next decade.
Current UK Defence Spending Plans
Current spending plans, which cover until 2028/29, show defence spending rising to 2.6% of GDP. However, Rutte's comments suggest that this trajectory is insufficient to meet the 3.5% goal without a clear plan for annual increases.
During his visit to the UK, Rutte met with key figures including Prime Minister Andy Burnham, Defence Secretary Wes Streeting, and Foreign Secretary Ed Miliband. He also engaged with defence industry representatives at a business park in Didcot.
Comparison of Defence Spending Targets
| Country/Alliance | Current Spending (% GDP) | Target Spending (% GDP) | Target Year |
|---|---|---|---|
| United Kingdom | 2.6% (by 2028/29) | 3.5% | 2035 |
| Nato Average | ~2.0% | 3.5% | 2035 |
| United States | 3.5% | 3.5% | Met |
Key Takeaways for UK Defence Budget
- Nato expects the UK to outline a credible path of annual defence budget increases.
- The 3.5% GDP target must be met by 2035, requiring nearly £30bn more in spending.
- Current plans only show spending reaching 2.6% by 2028/29.
- Rutte's intervention signals growing pressure on the UK to accelerate military investment.
Implications for the UK Economy
A significant increase in defence spending could have wide-ranging effects on the UK economy. It may boost the defence industry, create jobs, and drive innovation, but it also raises questions about fiscal priorities and potential trade-offs in other areas of public spending.
Chancellor John Healey, a former defence secretary, has endorsed the target, indicating cross-party support for higher defence budgets. However, the timing and scale of increases will be crucial to meeting Nato's expectations.
