§ Mr. Milburn
To ask the Chancellor of the Exchequer how many full-time equivalent staff were employed by the Inland Revenue on tax evasion investigations and at what cost in each of the last five years. 
§ Mr. Jack
Approximate numbers of staff units—full-time equivalent staff—and their cost, are as follows:
Staff units Cost £m 1990–91 3,200 103 1991–92 3,400 115 1992–93 3,500 124 1993–94 3,800 137 1994–95 4,400 166
The figures for 1994–95 cannot be compiled on a basis exactly comparable with earlier years, owing to a change in the way these figures are maintained. Unlike previous years, they include details of staff employed on all employer compliance work.
