I'm glad the Minister has learnt that lesson, and I agree with what he's just said. In terms of Cardiff, I think the south Wales metro offers a great opportunity for increasing public transport use instead of car use as employment is increasingly concentrated at the centre of Cardiff. But for Newport, the employment is disproportionately in business parks strung out along the current M4, and isn't the Minister correct in at least implying that what's really needed to help people to get to work around Newport, whether by car or by bus, is to get on with building that M4 relief road?
