But how would we know that it's being used effectively if there isn't something to aim for?
Which brings you back to the question about evaluation. We need proper evaluation of the various programmes that we have.
Yes, but without a target, how can you properly evaluate? If you don't know what you're trying to do, how can you properly evaluate? Anyway, you're open to suggestions about having a target, which is great. Would you agree that Government could use the revenue that's being produced through the levy on soft drinks towards some of these efforts to—?
Well, of course, there are some consequentials that are coming to the Welsh Government as part of the levy on sugary soft drinks. That funding, of course, is less than we had anticipated, and that reflects, actually, a success story because industry is reformulating, and so the amount of sugar in soft drinks is already starting to decrease, which is a good thing. But to your question: should we use the funding? Well, of course we should use funding. I'm not personally in favour of hypothecation, I think I'm more interested in the totality of resource that goes into public health programmes than into marginal resource. There are, of course, a number of initiatives that we currently fund through the general revenue. And when I think about obesity, I don't just think about the relatively small marginal amounts of money that come in through whatever source, but I think about the totality of the £7 billion we spend in health and social care and how we can divert and channel some of that towards broad prevention initiatives in general, and towards tackling being overweight and obesity in particular.
