That is a very good point, and it is something that the Scottish Parliament and the Scottish Government are extremely concerned about, because doing something that is utterly unnecessary will take up a great deal of their time.
The tactic is fraught with danger, as it introduces another totally unnecessary Brexit cliff edge, which will be welcomed by no one outside the inner sanctum of the European Research Group. It is further evidence of panic at the heart of the Brexit project. They know the wheels have come off and their Government are disintegrating before their eyes.
Finally, I repeat: this Bill should be withdrawn. It is a throwback to different times, and if the new Prime Minister is serious about making a fresh start and resetting relationships with Edinburgh, Brussels and the people of these islands, then abandoning this ill-judged piece of UKIP-ery would show that he is serious.
