asked the Secretary of State for Scotland if he will estimate the approximate cost of granting relief to proprietor managed businesses in Scotland in order to restrict the increase in their commercial rates bill for 1985–86 to an amount not exceeding (a) 125 per cent., (b) 133⅓ per cent. and (c) 150 per cent. of their corresponding 1984–85 rates bill.

Entries on the valuation roll do not permit identification of properties which might be in use by owner-managed businesses, so the information on which to base the estimates requested is not available.
