Boris Johnson's Dreadful Air Quality Record

Boris Johnson's awful record on air quality is confirmed once again.  This is just the kind of issue, requiring technical detail, persistence and long periods without exciting photo opportunities that you would expect the Conservative Mayor to fail in.  Indeed, I suspect more recent activity by Boris is not to do with the thousands of Londoners who avoidable die because of poor air quality each year, but more to do with political embarrassment from EU fines.
