asked the Secretary of State for Air what steps he is taking to ensure a sufficient supply of kerosene for jet propelled aircraft of the Royal Air Force.

Supplies of kerosene are obtained by the Air Ministry under contractual arrangements with the oil industry, and there has been no difficulty in obtaining the requirements of the R.A.F. The technical and supply questions arising from the increased consumption which is to be expected in the future are under active consideration.

Can the Minister say whether, in view of the expansion contemplated in jet propelled aircraft, the plans of the oil refining companies are going to keep pace with the demands for kerosene in the future?

That question had better be addressed to my right hon. Friend the Minister of Fuel and Power.

Is the Minister aware that agricultural tractors consume a great deal of paraffin when they could burn petrol, and so ease the load on the refineries?

That is another question.
