HC Deb 17 November 1970 vol 806 c368W
Mr. Gorst

asked the Chancellor of the Exchequer what is his estimate of the total amount owed by Government Departments to United Kingdom firms in respect of work done or equipment delivered, but for which full payment has been delayed due to unresolved queries or other causes.

Mr. Maurice Macmillan

I regret that this information could not be assembled without a disproportionate expenditure of time and money.
