I thank the Minister for the long and comprehensive—and occasionally interrupted—answer. There is an issue here. I accept that it is a political decision, of course, and we are all operating on that basis, but I am still worried and puzzled about the way in which this table of tariffs has been devised. I have heard nothing from the Minister to suggest that it is not arbitrary. In particular, he did not answer my question so perhaps he can do it now. Were the figures devised on the basis of some target saving being set
and then working backwards to say what the tariff would be to generate that saving? If that is the case, we ought to be told.
