Just reflecting on a point you made a little earlier about the practical implications of one of the recommendations, and David Melding made the point: the Permanent Secretary had assured the Public Accounts Committee that the Government would stop this practice of accepting things in principle and be clear when they were rejecting it. I've written to the Permanent Secretary again this morning, asking her to reinforce that ruling in the light of this report. There will be times, of course, when it's not possible to accept it, but do you accept that it would be better to be clear about the reasons for that rather than accepting in principle?
