For the last 15 months, Ryan Gallagher has here been chronicling the debate around the Alternative Vote (AV) referendum for OurKingdom.

Throughout this period there has been strong argument, controversies and bickering. At times the coalition government's relationship has appeared fragile as a result of differences on AV. Lib Dems accused the No campaign, which is heavily funded by Tories, of lying. While Tories, including prime minister David Cameron, refuted the claims, branding AV as "undemocratic".

Polls showing the level of support for both Yes and No camps have lacked any consistency. The Yes campaign enjoyed a substantial early lead, however gradually their support has waned. In recent weeks there has been a surge in support for a No vote, and two of the most recent polls put the No2AV campaign in a huge lead.

The outcome still remains uncertain. But whatever the result, when the polls close on the 5th May, it is clear that the AV referendum will have changed British politics for better or for worse – depending upon which side of the fence you are sitting.

With less than 24 hours until the ballot boxes open, both Yes and No sides both claim to believe they will win. It is now up to the voter to decide.

If you have not yet made up your mind, help inform your judgement by reliving the months of debate below....

• Lord Ashcroft produces research which suggests that the Conservatives "could do as well, and possibly better" under AV.
• Charles Moore of The Telegraph writes that “[first past the post] seems fairer and more decisive than any alternative vote.”
• The Daily Mail’s Anthony King describes AV as “nothing if not exotic.”  Adding: “anyone who claims to know how it would work out in practice in the UK is a false prophet.”  Another Mail columnist, Peter Oborne, says AV “enables politicians to break their promises, opening the way to secrecy and deceit.”
• Alexandra Runswick, Director of Unlock Democracy, releases a statement in which she says: “This referendum must not be derailed by politicians who have a vested interest in maintaining the status quo.”
• The shadow Welsh Secretary, Peter Hain, comments that Clegg has “allowed himself to be sandbagged by his Tory partners in his otherwise laudable attempt to intro

  

  duce a fairer electoral system.”
• A BBC documentary suggests Nick Clegg “bluffed the Conservative leader, David Cameron, into offering the Lib Dems a referendum on a change to the voting system as part of the coalition talks.”
• Co-chairman of the ‘All-Party Parliamentary Group for the promotion of first-past-the-post’ (see this document (pg.198) for more info on this group), Daniel Kawczynski MP, writes that he believes the problem with AV is that it “allows... two classes of voter, those who will cast one vote and those who will have two or three bites of the cherry.”  This, he says, results in an “unfair weighting of votes between those who support and often campaign on behalf of a certain party and those who are happy to vote two or three times.”
• Prime Minister David Cameron will campaign against AV, Downing Street officials confirm.
• John Prescott MP says AV is “cover for the biggest gerrymandering of seats that I have ever seen in my 40 years in politics.”
• Blogger Sunny Hundal describes his frustration with “the attitude of many lefties on electoral reform” who are opposed to the Alternative vote.  "AV offers more choice, even if it’s not proportional," he argues.
• Lib Dem MEP Edward McMillan-Scott believes there are better voting systems than AV.  The single transferable vote (STV), he says, “is the best form of PR because every vote counts.”

June

The hustings for the Labour leadership campaign gets underway, and all five candidates pledge to support AV, though none support PR.

• “AV isn’t worth having,” writes Anne McElvoy in Prospect.
• Writing from the perspective of New Zealand, Tan Copsey suggests without adopting AV the UK will remain locked in the past.  “Voting in Britain was like voting in New Zealand in the 1950s”, he says.
• According to campaigner John Wilhelm, the Alternative Vote has “serious weaknesses” and “does a poor job of reflecting voters' preferences.”  Wilhelm advocates “approval voting” because it “allows a person to vote both sincerely and strategically at the same time to better reflect his or her preferences.”

May

With the general election producing a hung parliament and a mismatch between votes and seats, Take Back Parliament organises a series of rallies in London and across the country. Nick Clegg is taken by surprise during coalition negotiations.  Guest speakers at rallies include George Monboit, Mark Thomas and Anthony Barnett.  The Coalition Agreement commits the Lib Dems and Tories to a referendum on AV.

• John Curtice writes that with or without AV, we can expect more hung parliaments in the future.
• AV is explained by the Guardian, complete with animated graphics.
• Support (or lack thereof) for electoral reform is “a generational thing” according to an unnamed shadow minister.

February [2010]

Gordon Brown makes a commitment to an AV referendum

• Next Left list “five reasons to be cheerful about the Alternative Vote.”
• The New Statesman outlines how AV would have affected the election outcome in 2005
• Lib Dem MP, Chris Huhne, comments that AV fails “to give voters the power they should have,” and “also fails to remedy the unfairness of the present system.”
• An interesting exchange between Stuart Weir and Andy White on AV takes place on OurKingdom.  The AV campaign is a “foolish crusade,” says Weir, and “as a whole would produce an unrepresentative parliament, and so adds spurious legitimacy to a bad system.”  White counters that AV would in fact “improve MPs’ legitimacy, introduce voters to preferential voting, and help persuade the political classes that the public has an appetite for reform.”
