Yes, I guess we all are anxious to talk about that.
The most important point is exactly what you've said, that as auditors, we base what we do on objective criteria; we don't make it up or we don't make up policy commitments, but take what the government has said. As your question points out, it is very much a challenge when we do our work.
There's a surprisingly broad range of places where we can find quite objective criteria. Often they are in the law itself, as the laws Parliament has passed often have quite explicit requirements of government departments. So that's one of the first places where we, as auditors, would look. Secondly, we would look at key commitments the government has made in its successive budgets and speeches from the throne. We've mentioned several times now the sustainable development strategy, which is often a very important place where we can find quite clear commitments from the government.
So it's really in that realm, where there are clear commitments, where we focus our work.
