Thank you.
Thanks. Siân.
The last question from me, about partnership working. You're putting an emphasis on the whole-system approach in implementing the plan, how are you going to create a system that co-ordinates action and drives change across relevant partners, avoiding a situation where it's everyone's role, but nobody's responsibility? How are you going to avoid that?
It's a very important question, and one of the four strands in the consultation is exactly related to that, around leadership and drive nationally. I'm not interested in producing a strategy that sits on a shelf. If you look around the world, there are plenty of obesity strategies. You may notice, by the way, that we've chosen not to talk about an obesity strategy but a healthy weight strategy, because I think having a positive construct is really quite important to us here in Wales. But leadership will be really important, and we will need some sort of structure to lead this, to provide oversight. I'm not a great believer in creating new structures, so we do need something that will give that drive, but the leadership comes from the top down. We need political commitment to this, and that's why I welcome the input from this committee. So, that needs to be assured. And then we need to make sure that the public sector generally is engaged in this, but it goes way beyond the public sector, of course, because we have to work with industry, and we have to work with communities, and we have to work with the public on this. So we need to think about our governance system for this and how we drive it forward. Interestingly, we had quite a large discussion two days ago between health and social care, but also involving the third sector and some members of the public, around how can we drive prevention more generally. It wasn't specifically on obesity, but of course obesity came up because it's such a pressing issue. This question of governance was discussed quite extensively, and we do have governance systems, of course, in Wales. We have public services boards, we have regional partnership boards, and how we can get those aligned behind this common agenda is really important. But I'd like to see—and I know I'm a public health professional, so I know that only maybe 10 per cent, 15 per cent, possibly 20 per cent of what makes and keeps us healthy as individuals and as communities can be driven through the health system; but I would like the system to step up and take these kinds of issues more seriously as well. So I'd be looking for local leadership through directors of public health and indeed through chief executives to work with their public services boards on this. So, we'll need some sort of national oversight, absolutely, but we need local ownership and local leadership, too.
