HC Deb 22 July 1985 vol 83 c407W
Mr. Mason

asked the Secretary of State for Social Services if he has yet received the medical advice concerning the relationship between chrysoidine dye and urothelial cancer that he called for upon receiving the special case control study by Birmingham researchers; and if he will make a statement.

Mr. Kenneth Clarke

A sub-group of the Committee on the Carcinogenicity of Chemicals in Food, Consumer Products and the Environment has considered this study. We are still awaiting its advice.
