Finance Bill

The hon. Gentleman's argument is absolutely right. However, advisers and promoters are coming up with schemes right now, and there is a real risk of loss of revenue yield and of individuals so engaged finding themselves subject to retrospective legislation. I am trying to work out where the balance should lie between the Revenue saying, "No, you can't do it—we're about to outlaw it", and allowing people to continue to develop these schemes and then finding that they are subject to retrospective legislation.
