Absolutely, and there are options like that. What you're doing is not restricting the right or the power, or whatever you want to call it, to advise prorogation; we are insisting that the House of Commons have a hand in making the Prime Minister accept responsibility for the consequences of his or her actions. That, I don't think, is very contentious. Perhaps it's a good way to go. But you must appreciate that you're not doing anything on prorogation itself. You're simply doing something on the order of House of Commons business.
