Bribery Bill [HL]

I am most grateful to the Minister for giving way. Could he explain what seems to be the rather difficult point here? He has produced an impressive list of matters for guidance and has accepted that there will be an ongoing need to look at it. What is the objection to putting a simple provision into the Bill that would require the guidance to be made on the face of the Bill for as long as it lasts, but without imposing any duties as regards the subject matter of that guidance?
