Parliamentary Voting System and Constituencies Bill

I am grateful to the noble Lord, Lord Soley, for giving way. I perfectly understand the legitimacy of arguments about the proper way in which one should reduce or not reduce the number of MPs. Where I do not follow him—and what seems an illegitimate argument—is for him to say, as he has said a number of times, that this is being done as a gerrymander, in effect. I put it to him that there is no evidence for that. What is the purpose of the Boundary Commission if it is not to ensure that any change in constituencies is fairly effected?
