HC Deb 08 May 1978 vol 949 c363W
Mr. Pavitt

asked the Secretary of State for Social Services why the expenditure on general ophthalmic services for 1976–77 was £1,735,673 less than the sum granted.

Mr. Moyle

The difference, 3.9 per cent., represents a margin of error in estimating expenditure on a demand-led service.
