Statement by the United Kingdom and the French Republic
on Nuclear Policy and Cooperation - July 2025.
The President of the French Republic and the Prime
Minister of the United Kingdom reaffirm their longstanding and
resolute commitment to nuclear cooperation. There is no greater
demonstration of the strength and importance of our bilateral
relationship than our willingness to work together in this most
sensitive area. In this regard, we commend the important
achievements since 2010.
Our nuclear weapons exist to deter the most extreme threats to
the security of our nations and our vital interests.Our nuclear
forces are independent, but can be coordinated and contribute
significantly to the overall security of the Alliance, and to the
peace and stability of the Euro Atlantic area.
As we have explicitly stated since 1995, we do not see situations
arising in which the vital interests of either France or the
United Kingdom could be threatened without the vital interest of
the other also being threatened. France and the United Kingdom
agree that there is no extreme threat to Europe that would not
prompt a response by our two nations.
France and the United Kingdom have therefore decided to deepen
their nuclear cooperation and coordination. A UK-France Nuclear
Steering Group will be established to provide political direction
for this work. It will be led by the Presidency of the French
Republic and the Cabinet Office and will coordinate across
nuclear policy, capabilities and operations.
The United Kingdom and France reaffirm their full support for the
Treaty on the non-proliferation of nuclear weapons and for our
obligations under the treaty. We will coordinate ever more
closely to uphold and reinforce the international
non-proliferation architecture.
