Mr. Robert Watt:

I think I set them out earlier on. I had done that before in my previous role. There are issues with the final design. A decision was taken to move on this when it was understood that there was a final design. In actual fact, the design was not final. We know now that many of the specifications were not correct. That has led to significant cost escalations. Mistakes were made. While the two-stage process was the right approach to adopt, errors were made in how it was implemented, particularly in relation to in making the decision, which was understood to be on the basis of a final design. It was the case that the design was not complete at that stage.
