New UK-France Nuclear Steering Group Meets to Advance Cooperation Under Northwood Declaration

At the UK-France Summit in July 2025, Prime Minister Keir Starmer and President Emmanuel Macron affirmed their commitment to strengthening the UK-France nuclear relationship. They signed the Northwood Declaration which established the UK-France Nuclear Steering Group in order to provide political direction and coordinate bilateral work across nuclear policy, capability and operations.

On 10 December, the Nuclear Steering Group met for the first time in Paris, jointly chaired by senior officials from the UK Cabinet Office and the Presidency of the French Republic.

They were accompanied by senior military personnel and officials from Defence and Foreign Ministries to discuss Euro-Atlantic security issues and coordination of their respective independent deterrents. They discussed their approach to strengthening deterrence in Europe and confirmed their ambition for bilateral co-operation on nuclear deterrence.

They also observed operation POKER which was the first time foreign officials were given access to this demonstration of France’s Strategic Nuclear airborne Component.
