I thank the Cabinet Secretary for his answer. We've heard from businesses, of course, who will face financial difficulty due to delays. There are the obvious frustrations and inconvenience to residents. Can I ask: when did you become aware that the project would likely go into an overspend situation? What provisions were made by the Welsh Government to cover the potential cost overruns of the scheme? Also, if the Welsh Government is liable for a proportion of the total cost of the overspend, what is that proportion? If you don't know what that figure is, can I ask why not? How was a procurement contract agreed for a project of this scale without your Government protecting taxpayers from an overspend that they're not responsible for, if that's the case? In addition, I want to ask what independent technical advice was sought by the Welsh Government in relation to many of the complex challenges associated with the scheme, importantly before the tendering specification was drawn up.
