Minister, one of the consequences of COVID is that we've seen a lot of our urban spaces being reshaped at a greater pace than any time in the last 25 years: one-way systems for pedestrians, no-traffic zones, suppressed traffic anyway. We've also seen greater calls for certain areas to have much more regulation of traffic, and other cities around the world, such as Paris, are beginning to exclude traffic other than for residents from large areas so there are more open spaces for children, for instance, to play in. All this has a great benefit for air quality. Will you be co-operating with your colleagues to ensure that this sort of approach is going to go forward as part of the clean air plan, because planning our environment, our urban areas, our traffic flows is essential to this?
