The hon. Lady is talking about returns. Does she recognise that a 40% return on an investment fund is extraordinary? One does not have to be a City hedge fund manager to understand that. A lot of that is down to the fact that the Government are a guarantor. Does she agree therefore that regular reviews should take place and that the percentage should be variable, based on the performance of the fund, as 50% or 90% of nothing will be nothing for the miners?
