asked the Secretary of State for Scotland if he will state, for each smoke control area order so far confirmed, the Exchequer grants paid to date in respect of adaptations required to private dwellings, the number of dwellings concerned, and the average grant per dwelling.

Under the 46 orders which have been approved 67,000 private dwellings are estimated to qualify for conversion grant. The total Exchequer grant is likely to be about £800,000 or about £11 16s. per dwelling on average. I am sending the hon. Member a table with details for each area.
