HC Deb 16 March 1983 vol 39 c207W
Mr. Benn

asked the Secretary of State for Defence if he will make available to the House the results of the investigations by scientists in his Department, under the auspices of the United States of America, into the alleged use of mycotoxins, yellow rain, as weapons in Laos and Kampuchea.

Mr. Blaker

No investigations are being carried out by Ministry of Defence scientists under the auspices of the United States of America. Our independent investigations are continuing, but we are not yet in a position to make a statement about the results.
