My Lords, I thank the Minister for his reply, which has helpfully taken us forward a little bit. The extension proposed is much more focused on the assured advice component of the primary authority, rather than inspection plans. But I will not pursue that at the moment. I welcome the repeated reassurance that consultation will precede any issue of guidance. That is helpful. I am certainly pleased to see the enthusiastic support of the noble Lord, Lord Deben, for this approach, and indeed that of the noble Lord, Lord Curry.
The wording “material extent” was simply a peg on which to hang an amendment so that we could have the discussion that we have just had. I accept entirely that if it appeared in its current form in the Bill it would not be particularly helpful. I thank the Minister for his comments and I beg leave to withdraw the amendment.
