Comprehensive Test Ban Treaty
- Question
-
To ask the Secretary of State for Defence, if he will publish the review made of the Comprehensive Test Ban Treaty (CTBT) methodology as mentioned has been undertaken last year in the Defence Nuclear Enterprise 2025 annual report.
- Answer
-
The United Kingdom has no plans to publish its Comprehensive Test Ban Treaty (CTBT) methodology. The methodology revalidated our approach to warhead design and certification which is, and will remain, in compliance with the CTBT. We ratified the CTBT in 1998 and we are committed to our voluntary moratorium on nuclear test explosions, having ceased nuclear testing in 1991.
