Parliamentary Voting System and Constituencies Bill

In July, my right hon. Friend the Member for Blackburn (Mr Straw) and I tabled questions about what estimate the Government had or had not made of the costs to local authorities, and the Scottish, Welsh and Northern Irish Governments. The answers that we got back eventually were that the Government had made no estimate at all. Is the Minister now telling us that he has made estimates of the additional costs, and if so, what are they?
