Question to the HM Treasury:

To ask the Chancellor of the Exchequer, with reference to the Government press release entitled UK to deliver on 5% NATO pledge as Government drives greater security for working people, published on 23 June 2025, whether the 1.5 percent to be allocated to resilience and security will include the costs of Sizewell C.

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.

Our National Security Strategy confirms our belief that these types of investment are vital to national security and we are pleased that this is now recognised by NATO. As set out in the Spending Review 2025, this government is making significant investment into these areas and we are confident we will meet the 1.5% target on defence and security related spending.

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