I have said that we must have a competitive coal industry. Equally, I agree with my hon. Friend that we do not produce enough of certain grades of coal—for example, anthracite and coking coal. That is one reason why British Coal has proposals to invest at Margam. To make that investment pay there must be flexible working and a new approach to working arrangements. Without those we will have to continue to import the coking coal that we could produce in this country.
