Air Pollution

I did not want to interrupt the flow of my hon. Friend’s speech, but now that he has been interrupted, I might as well. He too is a west London MP, so he is aware that Heathrow, in my constituency, is one of the most persistent air pollution hotspots. In the previous Government’s assessment, any expansion at Heathrow would have a significant impact on air quality. The latest airports national policy statement says it will have “significant negative effects” on air quality. We are one of the worst areas for nitrogen dioxide pollution, so does my hon. Friend agree that Heathrow expansion cannot go ahead?
