I think the main point is that the operating budgets will be frozen. That will be done within their votes, what's voted to them by Parliament. That is what will be controlled. It allows individual departments to then determine how they're going to meet that budget freeze.
I think each department will have different realities around their attrition rates. For example, one potential opportunity is for downsizing, and I think they need to look at that; they need to look at where they're going to be recruiting.
I guess the main point is that it's up to them to determine their future.
