HC Deb 13 July 1978 vol 953 c786W
Mr. Park

asked the Chancellor of the Exchequer what is his estimate of the amount of revenue lost to the Exchequer by tax evasion for each year since 1974: and if he will list the number of prosecutions for tax fraud over the same period.

Mr. Robert Sheldon

It is not possible to estimate the tax lost because of undetected tax evasion. On the second part of the Question, I refer my hon. Friend to my reply to the hon. Member for Leek (Mr. Knox) on 11th July.
