Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to page 23 of the Defence Industrial Strategy: Making Defence an Engine for Growth, published on 8 September 2025, CP 1388, which trade unions will be designated as being part of the defence industrial base.

Through the Defence Industrial Strategy we are taking a ‘whole of society’ approach, where both traditional defence and dual use manufacturers are included in a broader UK defence industry.

Therefore, individual Trade Unions are not being classified as either inside or outside this new definition.

This approach encompasses all elements of the UK defence enterprise including major defence contractors, SMEs, academia and defence workforce.

At the Defence Industrial Joint Council (DIJC) the interests of the workforce are represented by a number of Trade Unions. In line with other members of the DIJC, the Trade Unions representatives are appointed through HMG’s Public Appointments Process, based on the expertise and insight they bring.
