I've recently been in correspondence with you on planning issues around a development that's very significant in the mid and west region at the moment, which is the expansion of poultry units. We've seen a lot of applications coming in for free-range poultry. It's a response to the market; it's a response, partly, to Brexit, I think. It's something about the industry preparing itself for the future. So, there's no problem with that, but the planning rules around these units do seem to be rather rooted in the past, because we haven't dealt with such a large number before. Natural Resources Wales say that they don't make any remarks around planning applications around these units if they are not intensive farming, but, in fact, free-range poultry can be as polluting, or potentially as polluting, as intensive poultry; it's the nature of the way the hens are kept, particularly when they're indoors. So, are you absolutely sure that the current planning regime for free-range and other poultry units is fit for purpose?
