I thank my hon. Friend for that intervention, but we already have our clean air strategy, as I said, and our local authority fund, which we have
recently increased by millions. I urge him to have a look at that fund and I urge his authority to apply. Many authorities are already taking their own measures because they know, for example, where the hotspots are. He makes a very sound point and the exposure target will really help those hotspots, which is why it is so important.
