asked the Chancellor of the Exchequer what is his estimate of the loss of revenue in a full financial year which would result from the cancellation of all increases in Road Fund licence charges, hydrocarbon oils duties, and additional fiscal burdens imposed on the road haulage industry since October, 1964.

As regards the hydrocarbon oil duty the answer is estimated to be of the order of £30 million. No corresponding estimate can be given for Vehicle Excise Duty on the basis of available statistics.
