There's an irony here in that I was the person who wrote the manifesto that proposed the black route and, of course, Mark Reckless was a member of a political party that was responsible for writing a manifesto pledge opposing the black route. Look, I stand by the proposal that we made. However, I do recognise that times have changed since the black route was conceived. It's only responsible for Governments to accept—when times change, when new challenges are presented, to respond accordingly and to act in a nimble way, and that's precisely what we've done.

But I can assure all Members that we recognise that this challenge has to be addressed; 'do nothing' is simply not an option. The question for us is whether we are able to respond, packaging some of the alternatives in a way that will reduce or eliminate congestion—but also, at the same time, do so with less cost to the public purse. I believe that we can achieve a reduction in congestion on the M4 through Newport in a way that offers value for money and minimises cost to the public purse. Now, the commission's work has already begun. I have had an incredibly constructive discussion with Lord Burns about the work that's been undertaken to date by the Welsh Government, and how he and his commission will take it forward.
