Of course, I think the First Minister would accept that, on our side, naturally, we're going to say that we would have liked this decision to have been made earlier. There clearly is an opportunity cost in here, financially. Perhaps the First Minister could give us, actually, the full estimated total for the cost to the public purse, including the inquiry itself, the traffic modelling, surveying, design and legal costs. But there's also been potentially even bigger opportunity costs in terms of the time that's been lost—the eight years since your predecessor first took us down this path, which has ended up leading nowhere, frankly—which could have been invested, in terms of the energy, the effort, into an integrated public transport system that Wales so desperately needs. Obviously, we're particularly mindful of the problems that Newport faces—it's one of the most car-dependent cities in the UK—but it's also true, of course, that we need a vision for the whole of Wales.

Again, I mean this in the best possible sense, but we have to find a better way, surely, of making these decisions. There is a British disease, and we have a Welsh version of it, where infrastructure investment project costs are rising—we've seen the inflation in this case—the time that it takes to make the decisions is getting ever, ever longer, and, as a result of that, the third element, of course, is that public trust in the process by which we arrive at these decisions is being eroded. In this case, it has to be said that many, many people, seeing as they saw that promise in the Labour manifesto, will have had an expectation, which has now, of course, been dashed, and there has to be a response to that as well. 

Finally, setting up an expert commission—the response to any problem in Wales used to be setting up a committee. We've gone one better—we set up commissions now. Why set up an expert commission when we've just created an independent national infrastructure commission precisely to help us make better decisions in a more agile and adroit way? Why create another commission when we have one already? Perhaps the First Minister could address himself to that question.
