Can I say I share Siân Gwenllian's concern about second homes, especially when we have a homelessness problem, as we discussed earlier? I will again urge the ending of council tax exemption of houses registered for private holiday letting, which then get business rate exemption and that means people don't pay anything. That doesn't need primary legislation; that just needs action. But student accommodation and short-term lets for employment have been counted into second-home numbers on some lists. That's not particularly helpful. And you know in your own constituency that somebody came up with a third of the houses as being second homes when they're virtually all student accommodation. Does the Government know how many properties are second homes, i.e. used only part of the year or registered for holiday letting?
