Question to the Ministry of Defence:

To ask the Secretary of State for Defence, if he will update his Department's Fusion Doctrine to reflect lessons learned from the integration of civil society and private business responses as part of defence efforts in Ukraine.

Fusion Doctrine is not published by the Ministry of Defence as it relates to the UK's whole government approach to orchestrating National Security capabilities. Military Joint doctrine is reviewed continually by the Development, Concepts and Doctrine Centre through a five yearly plan. Review of Military Joint doctrine is required to reflect best practice and agreed lessons from operations and training.
