It has been made very clear in all the guidance and by the Prime Minister that, first and foremost, if people can work from home, they should do so. Those who have to go to work were advised to go by car, and also to cycle and walk. I thank the hon. Gentleman very much for his question, because he strikes a good note. He will know that the uptake of cycling has surged during this time, especially where businesses are providing a scheme so that their employees can have bikes. He will also know that the Prime Minister has announced that we are phasing out new petrol and diesel vehicles by 2035—earlier, if possible. Lessons will be learnt. The Air Quality Expert Group has been conducting a big survey, and I know that the hon. Gentleman will be interested in the results when they are revealed.
