We've legislated to allow local authorities to charge council tax premiums on second homes. As I said in the answer earlier, it's the responsibility of the Valuation Office Agency—independently of the Government—to determine the status of each property in Wales. As I said, those second home owners who try to game the system could find themselves facing very large backdated bills for council tax. But, again, I refer to the answer I gave earlier, where a review is being conducted, to examine the scale of the problem in different parts of Wales.
