Question to the Ministry of Defence:

To ask the Secretary of State for Defence, with reference to page 31 of the National Security Strategy 2025, CP 1338, published on 24 June 2025, whether he made progress on enhancing the Combined Joint Expeditionary Force with France at the France-UK summit in July 2025.

The July 2025 UK-France summit saw a complete overhaul of the Combined Joint Expeditionary Force (CJEF) into the Combined Joint Force (CJF) with significant changes to structure, focus, coordination mechanisms and leadership. This is outlined in the Lancaster House 2.0: Declaration on Modernising UK-French Defence and Security Cooperation press release of 10 July 2025.
