I thank the hon. Gentleman for that intervention. We have met many, many times and we share a common interest in this issue. We are not arguing about its importance—[Interruption.] He is encouraging me—I thank him, but I do not need any encouragement actually; we realise how serious this is. The point is that we will be setting the target and we will be showing the world. We will announce that target next October, but we will consult on it before that. It would be wrong to set, for example, a specific number, if, indeed, we found that that number should be lower. I will leave it there.
We have to have a public consultation on this issue and we will do so early next year. Members of the public will want to understand not only the health impacts, but what impacts the measures that will be taken will have on their life. But we will not be sitting around. The consultation will allow us to bring forward the final target in October, and we cannot miss that target.
