Mr. Paul Quinn:

As the Deputy said, hindsight is always a fantastic lens to look through anything. With the benefit of hindsight, I strongly agree with what the PwC report says about the independent challenge function. We put a lot of reliance on the design team we put in place. As Mr. Breslin said, we set a 95% cost-certainty objective for that design team. We relied on that. As he also said, in hindsight an independent arm's-length technical review would be helpful. I must caution that such a review is not cheap. It is not a question of hiring somebody for a couple of days to come in and look at it.
