Member for Mid-Sussex (Mr. Renton) Official Report, column 524, whether, on his visit to Moscow, in addition to the emphasis on the importance of verification in arms control, his hon. Friend also exchanged views on the detailed outstanding problems that hold up the verification of a comprehensive nuclear test ban treaty.

§ Mr. D. E. Thomasasked the Secretary of State for Foreign and Commonwealth Affairs what plans his Department has to prepare any new technical policy papers on new developments in verification measures for the ad hoc group of scientific experts on nuclear test ban verification which meets in March under the auspices of the United Nations conference on disarmament.
§ Mr. RentonThe value of producing a further paper is kept under review. But so far there has been only one technical paper directly responding to the United Kingdom's paper CD/610 of July 1985. Meanwhile we look forward to participating fully in the work of the ad hoc group of scientific experts in Geneva.
