Has the Prime Minister also considered that, far from the Russian position being as stated by him on 11th November, their draft treaty presented to the Geneva Conference on 31st October provided both for the ending of tests and for their effective control and that, moreover, the chief Russian delegate there, in the speech now published, made it quite clear that the Soviet Union is ready to conclude immediately an agreement on the terms of nuclear tests parallel with the system of control proposed by the experts"? In these circumstances, will the Prime Minister suggest to the Foreign Office that it is not helpful to continue its propaganda and to say that the only obstacle to any progress in this matter is the reluctance of the Russians to agree to control?
