asked the Chancellor of the Exchequer (1) what percentage of No. 714 forms his Department found proved to be untraceable to any person paying tax in the latest 12 months for which figures are available; what this number of forms was; and what was the amount of tax thus lost;(2) how many different names purporting to be names of sub-contractors appeared on all No. 714 forms in the latest 12 month period for which figures are available.

The form No. 714 is the tax certificate issued by an Inspector of Taxes which is retained by the subcontractor. I assume, therefore, that the hon. Member has in mind the forms No. 715, which are the vouchers returned to the Inland Revenue as evidence of payments made without de- ductions for tax. I regret however, that the information he seeks is not available.
