To ask the Secretary of State for Foreign, Commonwealth and Development Affairs, what steps he is taking to help prevent proliferation of (a) nuclear and (b) biological weapons.

The UK remains committed to supporting and implementing the Nuclear Non-Proliferation Treaty (NPT), a vital pillar of the international peace and security architecture. The NPT has created the non-proliferation framework that has both limited the spread of nuclear weapons and enabled safe access to nuclear technologies for peaceful uses. The UK contributes over £20 million each year to the International Atomic Energy Agency who ensure NPT compliance and hold member states to account on their obligations.

The UK is committed to universal implementation of the Biological and Toxin Weapons Convention. We will work with other States Parties to strengthen the Convention in 2025, fifty years after it entered into force. The UK's ambition for enhancing our own resilience, is set out in our Biological Security Strategy.
