There are obviously limits—one should be candid about it—in terms of rewriting history on these things. Decisions were made in the 1980s and 1990s and it is hard to reverse some of them. I have mentioned Harworth, where a particular case has been made. It has been mothballed for a couple of years and we are in discussions with UK Coal about it. We will listen to all representations that we receive about deep mines and their potential. The mines that are open provide an important indigenous source of fuel for Britain and will do so for many years to come.
