To ask the Secretary of State for Defence, what the (a) Infrastructure and Projects Authority and (b) Senior Responsible Owner rating was of the Joint Crypt Key Programme in (i) 2022 and (ii) 2023.

I am withholding both Infrastructure and Projects Authority and Senior Responsible Owner Delivery Confidence Assessment ratings for the Joint Crypt Key Programme as their disclosure would, or would be likely to, prejudice the capability, effectiveness or security of the Armed Forces. I would however be glad to offer the right hon. Member a briefing at a higher classification.
