The key issue is that, in very large measure, we knew what we were buying. We and the officials at Audit Scotland had long debates about this, and we agreed to differ on it, but our view was that we were close in a way that the Scottish Office had not been in the past and that we had good data—generally annual—on the major things that we were buying in respect of teacher numbers and different types of support staff that were coming through.Our intelligence, which enables us to spot issues, varied from adequate to very good.
