HC Deb 16 March 1977 vol 928 c231W
Mr. Brotherton

asked the Chancellor of the Exchequer what is his estimate of the number of building workers who will not be in possession of No. 714 tax certificates on 1st April of this year.

Mr. Robert Sheldon

It is impossible to give any estimate, since there is no way of discovering how many will not apply for a certificate.
