European Union (Withdrawal) Bill

Perhaps the Minister could help me with a clarification. As I understand it, the FCA and others have the powers he just described as a consequence of a cascade that comes, as he said, from higher levels of legislation that originated in a democratic process. They therefore have safeguards, frameworks, constraints, mitigations and appeals processes—all kinds of characteristics sitting around them. How do the powers of sub-delegation which the Minister described relate to any of those structures of cascade or framework, since we are supposedly leaving the EU?
