HC Deb 03 February 1969 vol 777 cc30-1W
Mr. Speed

asked the Secretary of State for Social Services what estimate he has made of the loss of revenue to his Department due to the employment of uninsured workers in the building and catering industries.

Mr. Swingler

No reliable estimate can be made, but the results of investigations at building sites and catering establishments suggest that the loss is small in relation to the number of persons employed.
