HC Deb 12 June 1968 vol 766 c42W
Mrs. Renée Short

asked the Secretary of State for Defence how many animals were killed last year at the Porton Research Establishment in experiments with chemical and biological war weapons.

Mr. John Morris

The number of animals used in 1967 in research on defence against chemical and biological warfare at the Microbiological Research Establishment and the Chemical Defence and Experimental Establishment, Porton, was 66,144. Home Office Regulations require that all animals used in experiments must subsequently be painlessly destroyed.
