My Lords, I have to say to the noble Lord, Lord Deben, that every alarm bell went off in my head when I heard the noble Lord, Lord Leigh, basically argue that this would be a route to get naked short selling on AIM. This is essentially a mechanism that will allow people to enter into contracts which they know if they had to fulfil they would be very unlikely to fulfil—talk about risk. That general underlying principle worries many of us who think that a less speculative financial services industry is, in the long run, much more sustainable than a far more speculative financial services industry. That is exactly the point. It is people selling short shares that they will not be able to buy if they are ever forced to close on the contract.
