Let me return to the quotation from Sir David Tweedie cited by my hon. Friend Mr. McFall. Sir David Tweedie was talking about the perverse financial incentives that can be obtained. He was not talking about tax, but about the corruption of the purposes of people who receive such stock options. I heard Mr. Flight say that they were used widely for ordinary employees. Employee share schemes are used widely, but not stock options. Those are a different kettle of fish altogether.
