I did see the letter inviting the Minister for Climate Change to meet with the UK Government Minister. Unfortunately, as you can imagine, our diaries get very booked up; we need a little bit more notice than three or four days. The Minister for Climate Change does work very constructively—as I did when I was in that portfolio—with the UK Government, and, obviously, our programme for government does commit us to improving water quality. Obviously, the River Wye pollution is something that has been very much in the media and very much in our postbags. NRW's initial assessment of P levels in our river special areas of conservation, and that included the River Wye, did indicate that the reason for the water bodies failing P targets was from a very diverse range of sources. The causes really are very complex, and I think that it's really important that we continue to work with NRW, that we continue to work with Dŵr Cymru, and that we continue to work with the UK Government.
