HC Deb 20 March 1980 vol 981 c328W
38. Mr. Cook

asked the Chancellor of the Exchequer what is the real value of receipts from capital taxation in the personal sector as an index of their real value in 1969.

Mr. Biffen

In view of changes in the structure of taxation since 1969, it is not possible without incurring disproportionate costs to provide the information requested.
