It looks as though, based on your own plan, in 2020-21, your FTE complements go from 16,000 this year to 13,587 next year. I assume that if you have the same amount of work and you're losing 2,400 FTE complements, that can only come from contracting, unless you're reducing the amount of work being provided through the service.
