I care about this issue and I know my hon. Friend cares about it, too, and it is true that many Members of Parliament on both sides of the House, but especially those who represent communities that suffer disproportionately from this, know that their constituents face a desperate injustice. The burden of this condition is not shared evenly across the country. It affects our population by class; working-class constituents are far more likely to suffer from it than middle or upper-class
ones. It affects our constituencies by region, too; there are regional hot spots, historically found in areas of heavy industry where people were very likely to be exposed to the dust, whether because they sprayed it on railway carriages or worked with it in the shipyards or as thermal insulation engineers and were not properly protected.
