I thank the hon. Gentleman for his question. According to our projections, Greater Manchester will hit, by being below, the 40 mg target, which is why it has not been included in the mandatory clean air zones. We are shortly about to consult on those, but the legislation is in place for Greater Manchester to put in that clean air zone if it wishes to do so; I believe in devolution, and surely it is a matter for the local council if it wants to take that forward.
