European Union Bill

I am sure the noble Lord is as expert on parliamentary sovereignty as I am. No Parliament can bind its successors; any Parliament can overturn a decision of a previous Parliament or even a previous decision of that Parliament. That is part of what we understand by the doctrine of parliamentary sovereignty. There is nothing we can do to prevent a future Parliament from undoing what we are doing. That is my limited understanding of all of this. Perhaps I may quote a greater constitutional expert than myself.
