David, it's possible. I think our preference would be, I have to say, to stick with the universal rate, because we know it's—. There's real simplicity and it's been welcomed in the sector. But the sector, also, are quite pragmatic about this. One of the defining hallmarks of the way that we've taken this scheme forward is learning in live time as we pilot and expand the pilots into different areas and different types of provision. If we learn lessons from that that suggest we need to come back and look at a differential in more-expensive-to-provide areas, then we'll have to look at that, but there might be other ways of splicing it. But first of all, I think we have to go in and see how does this work. We might find, Mark, we might find, David, that we go in and when everything is tallied up, the £4.50 per hour works in supporting provision there.
Okay. In your answer to John, you talked about affordability, which I totally understand. If I can now remind you: I don't remember the word 'affordability' coming in the manifesto pledge of the Government. It was 'we will offer childcare facilities'. So, I just want to put a reminder to you there.
Ministers always look at affordability.
Well, voters don't. In the situation regarding Welsh-medium, you answered that a little bit earlier, but I have concerns about capacity. Workforce capacity you've mentioned. To actually be registered you need staff who are qualified. There's clearly a need to get more staff, because in your own paper you say that the report in 2016 said you do not have the childcare capacity in Wales at the moment. Do you believe that you can actually deliver the workforce to meet that capacity, first of all through the English medium, but secondly through the Welsh medium as well? Because there's a clear need to look at it. You talk about 30 by 2020. By the way, 30 is nothing big when you consider the whole of Wales. Do you actually think you've got that workforce capacity set up before this is fully rolled out?
