Mr. David Moloney:

We would have been very engaged in discussions on MetroLink, which is a very large-scale project. We would have given views on that over the years and on the depth of the business case needed. At one point that would have been seen as delaying the project but what it did was give rise to a very comprehensive business case that very clearly articulated the financial risks. We discussed earlier the financial range involved and the unpredictability of a lot of the costs associated with MetroLink. That is a very large-scale project. We are in a better place than we were because we now have an external assurance process and a major project advisory group. These kinds of issues can be put to them, where there is a difference of view, to get an objective external view.
