Parliamentary Voting System and Constituencies Bill

My noble friend puts forward an interesting argument. This is an area on which I did some work in 1989 when we were designing the supplementary vote—we called it ““weighting””—and a number of the scenarios that we ran through lengthy computer runs were based on a reduced value being given to subsequent votes under the supplementary vote. I wish to ask my noble friend whether there might be a slight difference between what we were working on and what he was working on. When he moved the amendment, he referred to the value given to these additional preferences being based on the position on the ballot paper. I presume he meant that if a candidate was in seventh position and yet was the third preference of a particular elector, they would have only one-seventh of the value, whereas under the system on which we worked in 1989 they would have one-third of the value. Can my noble friend clarify the position? If he is working on the basis that there are seven candidates and the candidate at the bottom—candidate Peter—is the third preference of the voter but gets one-seventh of the vote for the third preference, I would not be altogether in favour of it. But if it is simply his intention that the first preferences of every voter should have 100 per cent of the value, that second preferences should have 50 per cent, that third preferences should have 33.3 per cent and fourth preferences 25 per cent, there is great value to the amendment. I understand that a number of academics have also worked on AV and supplementary vote systems since 1989 to establish whether weighting votes in this way would work. The only problem that arises if one does that is that the minority candidates—in this case, the Liberal Democrats say that they would gain more seats under AV—would not gain as many seats. Although AV tends only marginally to be more proportional—it some circumstances, it can be considerably more so—the effect of weighting votes in the way being suggested will be to reduce the likelihood of outsider candidates winning seats. My noble friend Lord McAvoy was worried about the anoraks. I apologise to him for being one of those rather pathetic creatures, but electoral systems is a particularly interesting subject. It is the sort of thing you go to bed at night thinking about. I welcome the amendment moved by my noble friend and look forward to the response of the Minister.
