Because of rounding, there may be an apparent discrepancy between totals and the sums of the constituent items. 2 Full-time equivalent includes those on career breaks or maternity/paternity leave. 3 Strength figures as at 31 March 2005 onwards include those staff on career breaks or maternity/paternity leave. Therefore these figures are not comparable with those provided for other years in the table.
