European Union (Withdrawal) Bill

My Lords, the reason I dare to intervene at all is that I have always had a great interest in conservation, as a farmer, and in looking after nature reserves and various such things. Will the Minister make something clear? It seems to me that the habitats directive and the water directives are already part of our law; I do not quite see how they would fall through in the absence of some of these clauses, but we do want to tighten up the legislation.
