Will the clean air Act, as you've been discussing with your ministerial colleague in the Welsh Government, be all-encapsulating, because we've been led to believe that obviously it will cover every aspect of life so that we can see a real improvement in the air quality here in Wales? As I said, 2,000 people approximately die prematurely because of dirty air here in Wales, and at many millions if not billions of pounds of cost to the Welsh NHS. Will it be a piece of legislation that will capture business, civic society and the whole gambit of Welsh life? Or are you looking at a more nuanced piece of legislation that will be more specific to areas of life here in Wales?
