Retained EU Law (Revocation and Reform) Bill

My Lords, the reason these amendments and this debate are important is that one always explores the general by probing the specific to see if it holds water. I wonder if, in that respect, it might be helpful for the Minister and the Committee if he defined in his response parliamentary sovereignty as against executive sovereignty. If we understood that more clearly, we would understand the status and the rationale behind what is proposed in this Bill, which I personally see as unnecessary.
