The other issue that raised its head was the cost of this, and I expect that the select committee will turn its mind to it. How many people is the Electoral Commission going to have to employ to manage the constant switching in and out of the rolls, especially as it gets closer to a by-election or to the general election? I can see it turning into an absolute disaster, especially when it goes right up to election day. So there is plenty of room for mistakes to be made there.
