Well, one doesn't have to not complement the other. I represent a constituency in mid Wales and, I have to say, it's very different to your constituency, with respect. You just can't—the public transport is not there. Unfortunately, to get to your nearest school, you're 10 miles away. You have to have an effective road infrastructure. But I don't disagree with you at all; I think they're compatible and both are important. We heard an earlier question today from Helen Mary Jones in regard to electric vehicle charging points and infrastructure as well, and we need to have road infrastructure for the expansion of electric vehicles also.

I will perhaps highlight some of the issues that I raised today in my questions to the Minister. The delays and the cost overruns associated with A465 Heads of the Valleys route, I'm afraid, perfectly highlight the Welsh Government's poor track record when in comes to the management and delivery of specific road improvement schemes. I mentioned a couple of others as well. Perhaps the Minister will have more time in this response to deal with perhaps how procurement and contractual agreements can change in order that we don't see these kinds of poorly managed schemes in the future.

One of the worst and most worrying examples, I think, of the Welsh Government's poor management of the road network in Wales is of course the level of ongoing congestion on the M4 motorway—a strategic road that has been blighted by huge levels of traffic congestion for many years, and the Welsh Government is yet still unable to provide an adequate solution to that problem. While the Welsh Government has been dithering and shelving any meaningful schemes, the volume of traffic on the M4 is increasing.

It is with huge disappointment, I think, that the First Minister—and I'm pleased that he is in here to listen to this debate this afternoon; I'm grateful for that—has made that decision not to proceed with the M4 relief road, in spite of the support offered by the UK Government and support from businesses across Wales and support from Members in this Chamber, including from the Government's benches as well, and of course as a result of the very expensive independent inquiry, which concluded that the M4 relief road should be built.

The Planning Inspectorate report found that the Welsh Government's assertion that it would be inconsistent with its declaration of a climate emergency is incorrect. The report found that

'the scheme would save about 4,324 tonnes of user carbon emitted on the Welsh road network each year, with increasing savings into the future'.

Furthermore, of course, the economic benefits of the M4 relief road are clear. With the economic benefits to building the M4 relief road outweighing the costs, the scheme would have been a good value-for-money scheme. Instead, the Welsh Government, of course, wasted that £144 million on the inquiry, only to reject its findings because it didn't suit the First Minister.
