asked the Secretary of State for Scotland if he will give the total expenditure on police services in Scotland in each year since 1975 to date at constant prices.

The information available is as follows:

Year	£ million (at cash prices)

1976–77	103
1977–78	109
1978–79	122

Public expenditure is now planned in cash and a constant price series of figures as used in previous public expenditure White Papers is no longer maintained. The most up to date published figures available at constant prices in respect of police expenditure in Scotland are contained in the minutes of evidence taken before the Committee on Scottish Affairs in June 1981—HC 364, Session 1980–81, page 29.
