asked the Minister of Agriculture, Fisheries and Food what proportion of margarine consists of animal fats, fish oil and vegetable oils; and of these, what proportion, on average, consists of imported materials.

Manufacturers' returns for 1981, the latest information available, show that animal fats represented 13£3 per cent., marine oils 48·7 per cent. and vegetable oils 38 per cent. of oils and fats used in the production of magarine. These returns do not separately distinguish imported supplies.
