Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what risk-assessment methodology is used to update the National Risk Register.

The National Risk Register (NRR) is the public-facing version of the National Security Risk Assessment (NSRA), which follows a rigorous methodology that assesses the likelihood and impact of the most significant risks to the UK and its interests overseas. Risks are presented as reasonable worst-case scenarios to allow planners to prepare for a severe but plausible manifestation of them.

The NRR and NSRA are updated via a dynamic process, meaning assessments can be updated as frequently as real-world evidence demands. To ensure that the assessment process is robust, risks are reviewed by panels of technical and scientific experts, each led by an independent chairperson. More information on the methodology can be found in the Guide to the NRR and Chapter 2 of the NRR.
