European Union (Withdrawal) Bill

I am grateful to the noble Lord. Can he elaborate on a statement he has just made? Four months ago, I asked the noble Lord who will be responding tonight to make it absolutely clear that the sovereignty of Parliament is supreme over everything that happens in this country, subject always to alliances, and that the sovereignty of Parliament could not be undermined by a referendum or by two referendums. Incidentally, for four months, the Minister has refused to respond to communications on this subject. The noble Lord has just said that we “ceded” sovereignty to the people though a referendum. Does he stand by that? Is parliamentary sovereignty no longer supreme in this country?
