Question to the Cabinet Office:

To ask His Majesty's Government whether the analysis of the implications of a nuclear attack, including a limited attack, on the United Kingdom set out in the Strath Report in 1955 has since been updated by a committee or body of equivalent standing; and if not, what consideration they have given to commissioning an update of that analysis in the light of current geopolitical circumstances.

The United Kingdom has well-developed contingency plans to respond to a wide range of eventualities, including nuclear attacks. The plans and supporting arrangements have been developed, refined and tested over many years.

The scale of these capabilities is driven by classified planning assumptions derived from the United Kingdom’s National Security Risk Assessment (NSRA), which is a classified assessment of the most serious risks that could cause a national emergency in the UK. An external publication, the National Risk Register, which excludes some security-related risks, was last published in 2023, but is based on the NSRA.

GOV.UK/prepare, the Government’s website for resilience and emergency planning, is designed to help people plan for potential hazards and equip themselves with the necessary knowledge and resources to respond effectively.
