Yes, I do absolutely agree with John Griffiths on this. He, as well as I, welcomes the latest report from Lord Burns and his team and the significant evidence base that sits behind that, and, of course, it recommends a significant upgrade to the south Wales relief rail lines as part of an integrated multimodal public transport network. This, of course, is something that John Griffiths has been promoting for his area for some time, and it does point the way to a more sustainable, long-term alternative to car use in that part of the world. I think that this is the right way forward, and we're very happy to work with John Griffiths and others to ensure that we can play our part in making that a reality.
