Nationality and Borders Bill

I promise that this is my final intervention on the Minister, but I do not understand why we have to have the provision at all. He is saying that it is perfectly open-textured enough, that good reasons do not have to be specified in the Bill because the Government are not going to put glosses on it or be overly prescriptive, that they can be objective good reasons or subjective good reasons, that it is only about having regard to the new principle that they are inventing et cetera. Why have this at all?
