asked the Minister of Fuel and Power whether he has given instructions that the sale of coal gas for the propulsion of motor vehicles is not to be permitted; and if so, under what regulation.

No, Sir. But my right hon. Friend has power to issue a direction under the Control of Motor Fuel Order, 1947, restricting the use of gaseous fuels, if this should become necessary.

Is it not a fact that a circular was sent round the regional offices instructing them that they should not grant permission for this purpose?

I am not aware of that fact.

Is my hon. Friend aware that there is considerable misunderstanding as to the circumstances under which gas can now be used for the propulsion of mechanical vehicles, and will he issue an authoritative statement to clear up this doubt?

I hope that the answer that I have given will do that.
