asked the Chancellor of the Exchequer (1) what is his estimate of additional tax receipts in 1979–80 if car benefits are assessed regardless of income levels;(2) what is his estimate of additional tax receipts in 1979–80 if car benefits were assessed on Automobile Association scales, and regardless of income levels;(3) what is his estimate of additional tax receipts in 1979–80 if petrol and oil used had been included in car benefits.

I will let the right hon. Member have a reply as soon as possible.
