Constitutional Reform and Governance Bill

I accept what the Minister is saying about memorandums being published at the moment, but if that is so, why is there any reluctance on his part to include in the Bill the requirement to publish memorandums in all cases? That would take away any opportunity that cynics might have to say, "Yes, that's what's usually done." The Bill gives a Minister the opportunity not to publish a memorandum, because he can decide to publish the details in whichever way he "thinks appropriate". By accepting the amendment, the Minister would be accepting that there is no option but for a treaty to be handled in this way, and he would not be leaving any discretion for a future Minister.
