I was copied in to the correspondence, and I think yesterday I wrote back to the man who did the original letter. I did note the concerns; I wouldn't say I share them. However, when anybody writes to me with concerns of that nature, I always ask my officials to look into them on my behalf initially, so they will be discussing the points that he raised with NRW. And certainly, if there are any concerns that I think I need to address, I will raise it with the chair and chief executive of NRW at my regular monthly meetings. Obviously, NRW do manage our NNRs. I think, again, they're very transparent in how they approach the management of them. I also think they set out very clearly in their strategies how they can improve the management of them. So, I will be keeping a very close eye, and if I feel I need to take steps, I will do so.
