Question to the HM Treasury:

To ask the Chancellor of the Exchequer, with reference to Minister for the Cabinet Office's Oral Statement of 24 June 2025 on the National Security Strategy, Official Report, columns 974-76, what estimate he has made of the proportion of GDP spent on broader resilience and security spending in the most recent period for which data is available.

The National Security Strategy 2025 was published on 24 June 2025. It confirms that by combining an increase in funding with recognition of the vital contribution the Single Intelligence Account plays to our national defence, the UK will spend 2.6% on NATO qualifying defence spending from 2027. This will be considered core spending.

NATO provides reporting guidelines for the 1.5% defence and security related spending. It will include investments that raise the overall resilience of our societies, such as energy security, telecommunications, and infrastructure, as well as the execution of defence plans, expanding industrial capacity and innovation and counter hybrid actions.

Along with all other NATO allies, the UK will report against the new categories of defence spending at the next NATO reporting deadline.
