My hon. Friend is making a really important point about the constituency link. That is a critical thing that ought to be protected. Since the Scottish Parliament was created, the number of constituencies in Scotland represented from Westminster has been reduced, so the size of the constituencies has increased. My constituency takes in two Scottish Parliament constituencies, so there are two MSPs. Having to cover the same ground as the MSPs often means that it is very difficult to maintain the same degree of link with the geography. Does my hon. Friend agree that that is a flaw in the system that needs to be looked at if we are proposing to move to a more proportional system?
