There is a real issue here in terms of something that is commonly called a "constitutional convention", and that is, if there's to be a change to electoral law, the convention is that it should be agreement between all parties in the House. There should be agreement between both sides of the House when there's a change to electoral law, so that we don't have the impression or the reality of laws being changed to benefit one party over another, so that we maintain a fair playing ground. The concern here is that the Labour Party is pushing through a change to electoral law without having that agreement across the House, in effect breaching that constitutional convention.
