Does the Prime Minister recall that in his letter to Mr. Khrushchev during the Cuban crisis he raid that the withdrawal of the offensive weapons would open the way to agreement on the first stage of disarmament and a nuclear tests ban? Does this not put a certain obligation on the Government to pat forward their proposals in these fields? Will he bear in mind that Mr. Khrushchev is under strong public criticism from Communist sources for saying that agreement can be reached with the Western Powers?
