asked the Secretary of State for Foreign and Commonwealth Affairs if he will make a statement on Her Majesty's Government's policy on chemical and biological weapons.

We have already stated that we believe lethal chemical weapons, probably including mycotoxins, have been used in South East Asia. The continued use of these weapons, as indicated by the latest American evidence, calls for vigorous condemnation by the civilised world and further demonstrates the need for early agreement to ban possession of these weapons. I am placing a copy of the United States Government's informative paper in the Library of the House.
