The point about the bill (soon to be Act) is that it is performance. It has long lost any connection to cost, legal obligations or actual outcomes.
Whatever the costs it sets an unbelievable precedent in terms of what a government can do. If you think as I do that the Conservatives are going to lose and badly, then literally they have broken through every last constitutional fetter going to do this. There are not many constraints at all on this elective dictatorship but the ECHR was one.
The supposition is that Labour would not be tempted with a huge majority to do similar in human rights terms. Well it can, and there will be nothing to stop it.
Interesting times the Conservatives are in for.
