Dr Julian Lewis: I welcome that robust response from the Secretary of State. Is he aware that, throughout the 1980s and early 1990s, when anxiety about nuclear deterrence was at its height, the Campaign for Nuclear Disarmament consistently produced strangely worded poll questions to get results such as that which has just been cited, but that whenever the British public were asked: "Do you think that Britain should continue to possess nuclear weapons as long as other countries have them?" poll after poll showed two thirds of British people in favour of retention and never more than a quarter against it?
