With reference to the Government press release entitled New Storm Shadow and missile cooperation to boost jobs as UK and France reboot defence relationship, published on 9 July 2025, who will command the new 50,000 strong combined joint force.

Detailed planning of the Combined Joint Force (CJF), evolving from the currently existing Combined Joint Expeditionary Force (CJEF), is currently under way with French colleagues following Thursday’s announcement.The current command structure of the CJEF under its Concept of Employment (CONEMP) is of a single operational commander provided by either the UK or France, appointed by both nations. It should be noted the CJEF is not a standing force, but made up of high-readiness forces available when it is deployed.All UK Service Chiefs, including VCDS and Commander Strat Comm, were consulted ahead of the agreement to create the CJF. Most significantly, on 24 March 2025 at the third annual UK-France All Chiefs meeting in London, the proposal was discussed with all of the French and UK Military Chiefs of Staff.

With reference to paragraph 35 of the policy paper entitled Security and defence partnership between the European Union and the United Kingdom of Great Britain and Northern Ireland, published on 19 May 2025, how many exchanges between the UK and the EU have taken place in relation to enhancing the resilience of critical infrastructure in Europe since 19 May 2025.

The Security and Defence Partnership agreed with the European Union on 19 May is an example of this Government delivering on our manifesto commitments to strengthen European security, support growth and reinforce NATO. Implementation is progressing. Since May, the Defence Secretary has held discussions with the European Commissioner for Defence and Space, Andrius Kubilius, where they discussed our ambition to explore the potential for enhanced UK-EU cooperation under SAFE. The Foreign Secretary has also held talks with the High Representative for Foreign Affairs and Security Policy, Kaja Kallas on the geopolitical challenges that face our continent. We look forward to the foreign and security policy dialogue between the High Representative, the Foreign Secretary and the Defence Secretary this autumn. In addition, officials from across Government continue to hold consultations with their EU counterparts on a range of issues, including but not limited to Iran, Russia-Ukraine, and tackling irregular migration. As the Defence Secretary has previously said to this House, he will ensure that any UK commitment– whether financial or non-financial – provides value for the UK taxpayer and supports our defence goals. We will continue to prioritise engagement and cooperation on the issues that are most important in helping to safeguard European security and prosperity – all in support of this government’s NATO First defence policy. The Defence Secretary and I look forward to continuing to update the House on developments. The Defence Secretary’s offer still stands that he is happy to arrange a discussion with the Member of Parliament for South Suffolk who has shown such interest in these topics.

Detailed planning of the Combined Joint Force (CJF), evolving from the currently existing Combined Joint Expeditionary Force (CJEF), is currently under way with French colleagues following the UK-France declaration announcement. This will be done in full consultation with NATO with respect to the Allied Rapid Reaction Corps (ARRC).As stated in the declaration the CJF will ensure the ability to plan and command a Combined Corps Capability. This corps can provide the Land component of a broader joint force combining all military functions, as part of NATO or bilaterally. The force will draw on corps level capabilities, including elements of the ARRC, as forces currently do under the CJEF Concept of Employment. It is not intended that the CJF will replace the ARRC, rather it will strengthen our warfighting corps through a deepened framework for interoperability and training.As this will be a NATO Strategic Reserve Corps, it is anticipated that the forces held at readiness for NATO will include those held at readiness for the CJF. The CJF will be fully interoperable and able to act in lockstep with the Alliance, whilst also providing a resilient framework for bilateral operations. The CJF will complement our already significant contribution to the Alliance.The current structure of the CJEF under its Concept of Employment (CONEMP) is for the use of high readiness national forces to respond to a crisis situation. There is no specified CJEF ‘state of readiness’. UK Troops offered to NATO as part of the Strategic Reserve Corps are currently held at Tier 3 with a readiness of 31-180 days.The current command structure of the CJEF, under its Concept of Employment (CONEMP), does not discriminate between using those forces already held at readiness for NATO or otherwise.
