If the hon. Gentleman will allow me, I shall deal with that later in my remarks. The receipts this year are affected by the earlier reduction of car tax from 10 to 5 per cent. Clearly that will affect the accrual for this year compared with last year. Also to be considered is the number of cars on which the tax is paid, and the value of those cars. I shall deal in some detail with past and future tax yields—the yield in future, of course, will be nil—and the estimate of the yield forgone.
