I will, of course, read the report as soon as it is published because, I, like so many MPs, have been waiting for a long time to see the outcome of that investigation. I thank the hon. Gentleman for drawing our attention to the report.
We also know that because of heather burning, water is more acidic and contains a higher concentration of minerals such as manganese, silica, iron, aluminium and dissolved carbon, and that it is left to the water companies to purify it, at the cost, of course, of the consumer. The cost of flooding is huge to the public purse—we have heard about the £2.5 billion that the Government have paid out or will pay out over a 12-month period—and also to the insurance industry and individuals themselves. Driven grouse shooting cannot be held responsible for all of that, but it can be a contributory factor, which is why we say that more research is needed.
