European Union (Withdrawal) Bill

My Lords, will the noble Lord clarify one thing? He suggested, I think, that we are going to continue with the European regime until the end of the implementation period, which would give time for consultation. Or will we move away from the European Union arrangements in March 2019? That is important. If we are to continue to maintain all European environmental regulations, as now, up to the end of 2020, then we are in a slightly different position.
