To ask the Secretary of State for Scotland what is the latest information available to him on the levels of leukaemia in the Rosyth area and the national average.

The latest published information on the levels of leukaemia in the Rosyth area and the national average is that contained in the study undertaken by the information and statistics division of the Common Services Agency into the incidence of leukaemia in Scotland which was published last year in the May edition of the Health Bulletin issued by the Chief Medical Officer of the Scottish Home and Health Department. I refer the hon. Member to the reply I gave my hon. Friend the Member for Tayside, North (Mr. Walker) on 9 July 1987 at column 245.
