Mark Rutte Urges UK to Increase Defense Spending to 3.5%

NATO Secretary General Mark Rutte visited the United Kingdom on September 16, 2026, to outline a new strategic vision for the alliance and press for increased defense contributions. During his visit, Rutte met Prime Minister Andy Burnham for the first time, visiting the Harwell Science and Innovation campus in Didcot to engage with the defense sector before delivering the 62nd Annual Lecture at the Ditchley Foundation in Oxfordshire.

In his lecture, Rutte introduced NATO 3.0, a framework envisioning a more European-led security approach where European members and Canada take greater responsibility for their own security and production. He characterized Russia's hostile actions as a sign of weakness and a symptom of Vladimir Putin's failure in Ukraine, asserting that such campaigns would only increase alliance support for Kyiv.

While praising the UK's commitment to security, Rutte warned that the West faces its most dangerous security environment in a generation. He urged the Burnham government to establish a credible path of annual budget increments to reach a defense spending target of 3.5% of GDP by 2035, a goal originally set by Donald Trump. Rutte noted that current UK projections of 2.7% of GDP by 2027 leave a gap of nearly £30bn and warned that the alliance can no longer assume the United States will provide the majority of military and financial support.
