Thank you, Andrew.
Welcome to all our guests. It's quite a remarkable thing; I don't think we could have invented this process if you didn't come to us with it. It reminds me of that Latin phrase, which I'm sure I will mangle, quis custodiet custodes, or who takes care of those who are supposed to watch over us?
Given the reverence, as you've heard, with which we hold our Auditor General, we're all kind of concerned that you might find something that we don't want to hear. But what would be the worst thing that you would be able to find? That would be a hypothetical situation, and then I'm going to ask you for a more concrete one. In other audits, what's the worst thing that you have found, or the most surprising thing that is perhaps of note to the citizens of the country where that audit took place?
