§ Mr. Andrew WelshTo ask the Secretary of State for Transport what has been the total cost to date, in 1986–87 prices, of the construction of the M25.
§ Mr. Peter BottomleyTotal expenditure in cash terms to the end of October 1987 on constructing the M25 has been £990 million. To provide an equivalent figure in 1986–87 prices would require revaluation of past expenditure to constant prices. Central records for past spending on some of the earlier sections of the road do not distinguish between years. It is not possible to obtain such information except by a manual search of files at disproportionate cost.
