Well, Llywydd, I'd definitely agree with the Member that land is a fundamental and expensive part of housing provision. It's why, for example, we have established a £14 million stalled sites fund in Wales, particularly valuable, I think, in Valley communities where there is land that needs investment in order to bring it up to a standard where it can be made available for development. There are further plans that local authorities in Valleys communities are putting to us as a Welsh Government to increase the investment we could make there alongside them to increase the supply of land that could then be used for housing and for other beneficial local development. It's why we are pursuing the idea of a vacant land tax, of course, as well, to make sure that where there is land that has all the necessary permissions to be brought into beneficial use, that that land is not artificially held back from being used for those purposes. So, I absolutely agree with what Leanne Wood has said in focusing on the importance of making land available for these purposes, and as a Government we are prepared to look at whatever policy initiatives we might be able to take beyond the ones that I've already outlined, in order to make sure that there is a good supply of land that will allow us to achieve the ambitions that I set out in answering earlier questions.
