My hon. Friend is absolutely right, but I think it is even worse than he says, because a price freeze would reduce competition. Not only would the big six put up their energy bills after the price freeze ended, but there would be less competition in the years ahead.
T2. Like many people across the country, I am suffering at the moment as a result of the poor air quality. Does the Secretary of State think that the poor air quality is due mainly to sand or to emissions from power stations in other parts of Europe? What is he doing with his European Union counterparts to ensure that we get energy security in Europe, because of the threat of Russia turning off energy supplies, and to ensure air quality in Britain by having cleaner power stations?
I am sorry that the hon. Gentleman is suffering—as he can see, I am too. He makes a valid point, because air pollution is a serious issue. Although it is the responsibility of my right hon. Friend the Secretary of State for Environment, Food and Rural Affairs, we take it very seriously. Most analysis shows that the air pollution that is most damaging in UK cities comes from the transport sector, but clearly we will do all we can. It is yet another good reason for going green.
