I don't think peer mentorship programmes are new; I think there are examples of that going on, in various different guises, in lots of different sectors. I'm very much of the view that this is something where people can support each other and that experience can be transformational—just knowing you're not alone when you're in a dark place is in itself something that is very helpful. I think the mentoring support that is there for parents as well as young people, for parents to understand what their children are going through, is also something that I think we can and do encourage. And there are examples, as you say, of best practice that we can pick up, and certainly the iceberg model that we've seen in Gwent, being led to a large extent by Liz Gregory, is something that we do hope that we can roll out to other parts of Wales.
