I thank the Minister for that, because it was extremely helpful, especially when he referred to the commissioner. I hope that later in our sittings we will get the chance to explore the independence of the commissioner in greater detail.

I note what the Minister said that was specific to the Control of Pollution Act 1974, but I wonder whether he shares my concern for the residents of Camden. Areas such as Drummond Street and Cobourg Street, which I had the privilege of visiting a few days ago, are remarkably quiet. There seems to be a misconception that people who live in central London are somehow well used to noise and bustle and therefore cannot be afforded the same sorts of facilities as those who live in quieter, more rural, pastoral circumstances.

Will the Minister give some thought to ensuring that some sort of parity of esteem between urban and rural areas filters through everything done in the name of HS2? There is no justification in my mind for people living in such areas as Cobourg Street—many of them elderly and disabled—having to suffer a level of noise that would not be tolerated under the scheme in rural areas. I do not know whether he can give me any assurances about that, but that is certainly something we are looking for.
