HC Deb 15 December 1989 vol 163 c839W
Dr. Thomas

To ask the Secretary of State for Foreign and Commonwealth Affairs what plans he has to encourage additional countries to join the nuclear non-proliferation treaty; and what information he has concerning attempts by the United States of America and the Soviet Union to convince additional states to join the treaty.

Mr. Waldegrave

We regularly raise the question of accession to the treaty with non-parties at various levels. The three depositary powers of the treaty, (the United Kingdom, the United States and the Soviet Union) attach importance to the wisest possible adherence to the treaty, and frequently discuss with each other their efforts towards this end.
