But you have spoken in the debate now and you have done exactly that, and I commend the Member for Monmouthshire in doing so.

But, of course, the tramways that I've described do all link down to the Monmouthshire and Brecon canal as well, and the Disgwylfa and the Llangattock tramway do link in with the wharfs down in Govilon with which he's very familiar. But I hope that, as the Government takes forward work on the Valleys taskforce, we will look again at the rivers of south Wales.

In recent years, public policy has been targeted at cleansing the water within those rivers, and rightly so; it's important. When I was growing up in Tredegar, I always considered myself lucky that the water I played in in the Sirhowy river was always brightly coloured, and nowadays I hope my own son would take a different view. But I hope, in replying to this debate, we can look again at the rivers of south Wales because our developments have, over decades and perhaps centuries, turned us away from our rivers, turned us away from the natural environment and not understood how fully that has shaped our own histories. And I think the rivers of south Wales—Malcolm Cross will tell me, and he's right—are the great undiscovered, neglected gem of our valleys.
