Mr. Des Carville:

It has evolved much more than that. I would not like the committee or the Deputy to think we just take something somebody says at face value without probing it. The auditing expression we would have used when training in KPMG once upon a time was "professional scepticism". We apply it to everything we do. Just because somebody says something is commercially sensitive we do not say that is fine. We probe and push to satisfy ourselves that there is a case to be made, but my point about the previous opening statement is that the committee will get a sense of its tone and what we were trying to do in it. In due course we will share that information with the committee when we come back and deliver a different opening statement.
