Former NATO chief General Sir Richard Shirreff says the UK risks “catastrophic costs” unless the Government increases and strengthens defence spending. In comments reported by the Daily Mail, Shirreff warns that delaying action could lead to serious consequences for national security, describing potential outcomes in stark terms and urging immediate steps to bolster readiness. The outlet frames the remarks as a direct warning to Keir Starmer and the Labour government, urging defence investment to reduce the likelihood of severe impacts. The reporting does not provide new policy details, figures, or specific timelines for any proposed increases. It also does not attribute the comments to a government response at the time of publication. Overall, the sources present a consistent message: Shirreff argues that improved defence capabilities now are necessary to prevent a higher-risk security environment and avoid potentially grave costs later.
