Question to the HM Treasury:

To ask the Chancellor of the Exchequer, pursuant to the Answer of 11 June 2025 to Question 59131 on Intelligence Services: Finance, if she will specify the total financial quantum of the greater elements of the Single Intelligence Account spend referred to.

In line with practice among our allies, and recognising the increased contribution provided by our security and intelligence agencies on defence, we are including greater elements of the Single Intelligence Account spend in our NATO defence reporting. This will bring total NATO qualifying spending to 2.6% by 2027-28. NATO sets the definition for NATO qualifying defence spending, against which the Government reports, in line with guidance provided by NATO. The SIA budget is set out in the Spending Review 2025 document. (Spending Review 2025 document - GOV.UK)

The inclusion of departmental spending that falls under NATO qualifying defence spending definitions will continue to be periodically reviewed in line with NATO guidance.
