Diolch, Llywydd. Thanks to Simon and the others for bringing today's debate, and I formally move our amendment. We do seem to have talked about clean air quite a lot lately in the Chamber, but, of course, the air quality is not signally getting any better, so I suppose it's still a pertinent issue, so we can talk about it again. And there are developments, as Simon Thomas made clear, in places like Berlin and other cities, where they are going ahead with various initiatives, some of which we do have reservations about: clean air zones—I'll raise that later on. But we, of course, agree with the spirit of today's debate in that we agree that we need to make moves to improve the air quality. So, in that respect, I gather most, or all, of the parties, in fact, would be in agreement.
