§ Mr. Skeetasked the Chancellor of the Exchequer what is the Government's assessment of the yield of PRT and corporation tax reaching in aggregate 70 per cent., 75 per cent. and 80 per cent. of taxable profits.
§ Dr. GilbertI take it that the hon. Member has in mind the total tax yield from the exploitation of oil and gas deposits on the United Kingdom Continental Shelf. Estimates of this total depend on the assumptions made, inter alia, about levels of oil prices and of costs of extraction over a considerable period of years.
