When Portcullis House was built, the final bill way exceeded the initial cost estimates. What responsibility will the Commission take to ensure that that does not happen on an even bigger scale?
Clearly, the answer will be a combination of the assessment that will be made and the normal following of procedures to try to stop that happening. I am very aware of that issue as a member of the Commission, and as the hon. Gentleman will know from my background, I do not like overruns.
