The Clause would not do what my hon. Friend wants it to do without this great risk of avoidance. We do not want to spoil the thing by its being open to abuse. I have great sympathy with the intention and spirit of most of the Clause but I think that my hon. Friend the Member for Nottingham, South (Mr. W. Clark) would agree that limitations really are necessary and must be devised to ensure that there is no avoidance.
