Intervention Stocks (Cereals) Sir Peter Hordern asked the Minister of Agriculture, Fisheries and Food what is the value of stocks of cereals held in intervention (a) in the United Kingdom and (b) in the European Economic Community; and how many months' supply this represents. Mr. Gummer Community intervention stocks of cereals were valued on 30 November 1986 at 2,977 million ecu (£1,967 million), including 791 million ecu (£523 million) for stocks in the United Kingdom. These stocks are equivalent to approximately 40 days supply for the Community of 12.
