I can assure you that we are having these discussions with local authorities in terms of their experiences of the issue, to what extent this is a problem. It does vary across Wales, I think, in terms of how many second homes there are and how many holiday lets there are, and it's certainly an acute problem in some areas. But it's one that we're really keen to address because, as I said, we've got a piece of work going on looking at the future of council tax, looking at different ways of looking at council tax, to try and make it more progressive, looking at land value taxes, looking at local income taxes—all kinds of different permutations of raising local taxation in future. And, certainly, this is part of it.
