asked the Chancellor of the Exchequer (1) what were the main reasons for the number of Inland Revenue staff actually employed falling below the authorised staff numbers in 1982;(2) what was the average monthly shortfall between the Inland Revenue authorised staff numbers and the number actually in post over the period 1 May 1982 to 31 December 1982; and what was the average monthly saving on the salaries bill as a result of any shortfall.

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