HC Deb 22 March 1977 vol 928 c528W
Mr. Ridley

asked the Chancellor of the Exchequer what estimate he has made of the cost to public funds of support for those put out of work by their not having No. 714 tax exemption certificates.

Mr. Robert Sheldon

None. There is no basis on which any estimate could be made, but I have no reason to suppose it would be significant.
