Dr DUNCAN WEBB: Well, you may scoff, Maureen Pugh, but the fact of the matter is we have to plan in this House for all eventualities and, whilst the Labour Party has been conferred a generous mandate, we know that there have been many Parliaments where one or two people could sway the entire House. To put that in the hands of someone who has been put into Parliament by their party on the very basis of their party allegiance, to say that that person can cross the floor, ignore entirely the will of the voters on a whim, is to make a constitutional tear in the fabric of this nation, and the right place for that to be decided is in exactly the way this bill has set it out.
