HC Deb 26 March 1970 vol 798 c496W
Mr. Doughty

asked the Chancellor of the Exchequer if he will estimate the cost to the Exchequer in a full year of changing the rates of motor vehicle duties to make them equal to the rates prevailing in October, 1964.

Mr. Taverne

I regret that the information, particularly that relating to goods vehicles, could not be obtained without disproportionate cost.
