§ Mr. Ray Powell
asked the Secretary of State for Wales, pursuant to the reply to the hon. Member for Dundee, West, (Mr. Ross) Official Report, 19 October, column 9, why information is not available of the number of persons in Wales with Down's syndrome.
§ Mr. Michael Roberts
A reliable estimate of the prevalence of Down's syndrome in Wales would require an extensive survey and there has been no such survey.
