My hon. Friend makes a very good point. He will have heard me refer to the M4 on many occasions as a vital asset that joins the European mainland to the Republic of Ireland. It is not just a Welsh road; it is of economic significance to the UK and more widely, and it plays a strategic role. That, combined with the slightly mysterious position that the Welsh Government have adopted on a moratorium on road building, leads me to the conclusion that he has reached, which is that there are better ways of maintaining and improving the UK-wide network, including roads that are exclusively in Wales.
