I support that treaty. I want to see a world free of nuclear weapons and I think that countries such as the United Kingdom should lead by example. Instead of spending tens of billions of pounds on a new generation of Trident nuclear missiles, we should get rid of Trident nuclear missiles from the Clyde. We will continue to support action for unilateral nuclear disarmament because, if countries lead by example, the world will be a safer place in the long term as a result. We will support action on that internationally from the UN and elsewhere, because it is the right thing to do morally, financially and for practical reasons.
