Former NATO Chief Urges Next UK PM to Address Rising Threat of War and Defence Spending

Former NATO Secretary General Lord Robertson has warned that the next UK Prime Minister must urgently address the growing threat of war. Speaking on July 7, 2026, he emphasized the need for increased defence spending as the UK prepares for a crucial NATO summit in Ankara, Turkey.

Concerns Over Defence Spending Delays

Lord Robertson expressed that Britain's NATO allies are "disturbed" by the delays in the UK government's defence investment plans. He described these plans as "unconvincing," noting that the £15 billion increase in military spending proposed by Prime Minister Sir Keir Starmer over the next four years may not be sufficient.

During the upcoming NATO summit, which President Donald Trump will attend, Sir Keir is likely to face pressure to accelerate defence funding. Lord Robertson criticized the current defence investment plan, stating that it has caused confusion within the Ministry of Defence and has unsettled the defence industry.

The Growing Threat of War

In his remarks, Lord Robertson highlighted that the challenge of increasing military funding to counter threats facing the UK is now more urgent than previously anticipated. He stated, "We are under daily attack at the present moment and that will be ramped up." He also warned of a potential Russian attack on NATO by 2030.

Sir Keir Starmer's defence investment plan aims to increase military spending to 2.7% of the UK's gross domestic product (GDP) by 2029 and is intended to meet NATO's target of 3.5% of GDP by 2035. However, critics argue that the absence of a specific target date to reach 3% of GDP is a significant oversight.

Future Leadership and Responsibilities

Lord Robertson advised that the next Prime Minister must reevaluate the defence investment plan. He noted that the new leader, likely to be Andy Burnham, must take the responsibility of funding the defence plan seriously. Burnham has publicly committed to ensuring the security of the nation without compromise.

• £15 billion increase in military spending proposed
• 2.7% of GDP military budget by 2029
• 3.5% of GDP target by 2035
• Potential Russian attack on NATO expected by 2030

As the UK navigates these pressing issues, the need for decisive action in defence spending becomes increasingly critical.
