Does not the Prime Minister recall that in his speech during the weekend of 1st June he announced that in order to maintain peace it was necessary to preserve Anglo-American superiority in nuclear weapons? Is that the right hon. Gentleman's own unilateral doctrine? If so, how is it proposed to achieve it? Secondly, how does he propose to get the Soviet Union to agree, in a disarmament treaty, to accept the superiority of the West in nuclear weapons?
