§ 11. Mr. Swinglerasked the Lord Privy Seal what is the total number of nuclear tests of all kinds which have been monitored to date by the British national monitoring system; and if he will state respectively the numbers of tests held by the Soviet Union, the United States. Great Britain, and France.
§ Mr. HeathThere have been 22 British nuclear tests. 195 United States tests have been announced by the United States Atomic Energy Commission. The French Government have announced four French tests. About 100 Soviet tests have been reported. It would not be in the national interest to give details of tests monitored by the British national monitoring system. I can only say that our system has recorded signals from certain nuclear tests.
