Question to the Foreign, Commonwealth & Development Office:

To ask Her Majesty's Government what assessment they have made of the impact of lifting the cap on the number of Trident nuclear warheads the UK can stockpile on nuclear non-proliferation.

The fundamental purpose of the UK's nuclear deterrent remains to deter other states' use of nuclear weapons. We would never encourage others to develop nuclear weapons in breach of their NPT obligations. We remain committed to multilateral disarmament and our shared long-term goal of a world without nuclear weapons.
