HC Deb 13 April 1927 vol 205 c349
10. Lieut.-Colonel WATTS-MORGAN

asked the First Lord of the Admiralty the amount paid during the last financial year for oil fuel for naval purposes, and the average price per ton; and whether he will give the approximate cost of producing the same amount of heating power if coal were used instead of oil?

Mr. BRIDGEMAN

It is not in the national interest to make public the information asked for.
