Minister, I have to say I was a little bit disappointed that the temporary 50 mph speed limit extension to the west of Port Talbot wasn't terminated this summer, as you indicated in a speech earlier this year. Of course, I accept that Welsh Government is in a bit of a bind at the moment regarding this court case around air quality and having to reduce, particularly, traffic congestion emissions, as a result of that court case. Even so, I think we still need to get some sense of perspective here, because, obviously, there's a huge amount of industrial pollution in the Port Talbot area as well. So, I'm wondering if you can tell me how you balance funding between central and local government attempts to tackle both traffic air pollution and industrial air pollution, and, particularly, the money that you give to local authorities—how you ensure that it's actually spent on improving air quality, as the money was intended to do.
