Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, what was the outcome from the UK’s participation in the Non-Proliferation of Nuclear Weapons Review Conference on a path to a) disarmament and b) non-proliferation.

The United Kingdom played an active role at the 2026 Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Although consensus on a final outcome document was not reached, the UK worked constructively to advance both nuclear disarmament and non-proliferation. The UK promoted practical work on disarmament through transparency, verification, irreversibility and strategic risk reduction, including through our chairship of the P5 Process. On non-proliferation, the UK championed the role of the International Atomic Energy Agency, safeguards, export controls and nuclear security, while continuing to support efforts to address cases of non-compliance. We will continue work to strengthen implementation of the Treaty, which remains the cornerstone of the international nuclear order.
