101. Mr. A. J. Irvine

asked the Chancellor of the Exchequer at what rate of consumption of motor fuel expressed as a percentage of normal consumption the level of receipts from tax on hydrocarbon oils, including the current shilling increase, would exceed the level of receipts from that tax in a period of normal consumption without such increase.

Mr. Powell

A little more than 70 per cent.
