Nuclear Disarmament

Question: To ask His Majesty's Government what plans they have for their term as chair of the P5 Process for 2025–26.

Answer: The P5 Process, established by the UK in 2009, remains an important channel through which the Nuclear Weapon States (NWS) discuss implementation of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). The UK will assume the 2025-26 chair of the Process this summer 2025, taking over from China. We will seek to convene substantive discussions on nuclear doctrine between the P5 states, and discuss nuclear risk reduction. We will also facilitate two accompanying non-government dialogues, the Expert-Level Track (ELT) and Young Professionals' Network (YPN). The purpose of these dialogues is to engage non-proliferation and disarmament experts and early career professionals from academia and think tanks in P5 countries, with the aim of generating new ideas to support the government-level process.
