So what happens? They get criticised for taking too much margin. Well, BP, they reported—and look, I know I'll probably get some smirks from the other side of the House saying, "Well, of course, they would say that." But these are people who understand the market. They say that when margins were low, between 2000 and 2010, we saw—this is when low margins existed for the fuel suppliers—almost 400 retail sites close and the exit of Shell from the industry. More recently, as margins have restored, we've seen expansion and investment, as we would expect, resulting in consumers now having the benefit of the broadest range of offers ever.
