Thank you for that answer. It seems that—. My concern is that, when the First Minister said that all these organisations had responsibilities for inspecting these tips—I just worry whether there's any overlap of responsibility where one organisation may not be clear who’s doing what. In respect of Welsh Government owned land, is it solely a matter for NRW to assure you and us? And where—. You said the landowner was responsible, but then you listed various organisations who might not be the landowner, for instance, if it's private land. What then is the responsibility of the Coal Authority versus the local authority in which that land is?
