We need to actually see some numbers around that and have some real effort, because what often happens is that Government departments write a regulatory impact statement early on, at the start of a bill, and say, "Well, we haven't actually got the detail. We don't really know, but we'll come back and come up with something more detailed later on in the process in the future.", and they never do. So once we've started the process, it just rumbles on and we never actually get to the bottom of it. So we just want to signal right here, right now, that we'll be paying very close attention to that.
