I was in full agreement with the hon. Gentleman until that last bit. Of course not. I was going to praise the work of Southampton City Council, which has received significant Government funding for its clean air programmes. It is doing a good job and should continue to do so. To be clear, as things stand, clean air zones can be implemented by any local authority. It should therefore be in the interests of all local authorities to do whatever they can to improve air quality for their local communities.
