Pit Closures Sir C. Osborne asked the Minister of Power how many miners are expected to lose their jobs as a result of the North Sea and mainland gas discoveries; how soon this will happen; which pits will be affected first; what profits or losses they have made in each of the last five years; and if he will make a statement. Mr. Marsh I would refer the hon. Member to what I said about this in the Adjournment Debate on 20th May.
