There's much I agree with in that response and, piecemeal, we see many, many good initiatives, and it's trying to combine them, and I just wonder if we need to look at traditional models that have not answered the problem to the extent that we would demand. They're basically treatment first models, usually based in hostel environments, rather than in a home that is then supported—you ensure that the person feels secure in their tenancy and in a home-based approach. But, as I said, the traditional models have been treatment first, and that's what you do before you put someone in a home of their own. 

Turning this around to a housing first model is a challenge, but already we're seeing remarkable success, for instance, in the project in Anglesey, which has been piloted by The Wallich foundation. We've seen some countries now adopt housing first, like Finland, where it's been remarkably successful. So, is the Welsh Government up to a fundamental review of the old systems—treatment first, generally—and looking at housing first?
