Parliamentary Voting System and Constituencies Bill

I am not sure whether I can still intervene on my noble friend before he sits down, but I put the point to him: he is right to have said that there needs to be a proper emphasis on numerical equality, and we have to get the question of local boundaries into the right perspective but not jeopardise the highly desirable objectives that the Government have of achieving numerical equality. However, does my noble friend think it acceptable that the tolerances should be so tight around the norm that the system will mean that county boundaries and even ward boundaries are routinely crossed?
