HC Deb 07 February 1972 vol 830 c284W
Mr. Skeet

asked the Chancellor of the Exchequer what amount of revenue he estimates he will obtain by placing a tax on gas for use as fuel for road vehicles.

Mr. Higgins

This will depend on the rate of duty to be imposed and the extent of the future use of gas as road fuel. The tax is however also necessary to safeguard the existing revenue from conventional road fuels.
