My Lords, I support my noble friend Lord Sharpe, having signed all the amendments in his name. There are two key principles at stake here, as he eloquently set out: first, not to introduce yet another definition and, secondly, to take the opportunity to bring some clarity, consistency and coherence of definition. This would not just be beneficial for this Bill but have benefits far beyond it. As he rightly set out, this Bill may not be the place for that second objective. It is obviously the place for the first but, if it is not the place for the second, it would certainly seem to provide the right level of focus and spotlight to enable the department to look at this and bring forward plans to have definitions and classifications that are clear and consistent but also provide what anybody in whatever size of business they are involved with needs. So those definitions are useful.
