Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answer of 7 September 2026 to Question 22947 on Nuclear Weapons, what assessment he has made of the effectiveness of the National Endeavour communications campaign.

We assess the effectiveness of the National Endeavour communications campaign through a range of measures, including reach and engagement across traditional and digital media platforms, and levels of awareness, support for and understanding of the nuclear deterrent. Public support for the UK's nuclear deterrent remains high, however, it is important to note that levels of public support cannot be attributed solely to the National Endeavour campaign, as they are influenced by a range of factors, including wider public attitudes, international events and the geopolitical environment. The campaign contributes to broader efforts to improve understanding of the Defence Nuclear Enterprise’s role in protecting the UK and supporting jobs, skills and economic growth across the country.
