Alternative Vote and other animals

Visualisation of electoral outcomesIt seems that our new ConDem government will be offering us a referendum on changing the electoral system used for general elections from First Past The Post to Alternative Vote (FPTP → AV). The pre-election manifesto status was that the Tories wanted to keep FPTP, the Lib Dems wanted proportional representation (PR), while it was Labour who were the party suggesting a move to AV. A few times the BBC made the mistake of suggesting that AV is a proportional system, but this is not surprising from reporters who are more concerned with personalities than electoral geekery.

There is some self-interest in the parties’ various stances. On the basis of votes cast in this last general election, the Tories would probably lose seats given any of the other systems, Labour would probably gain a few seats under AV, and the Lib Dems would probably gain around a score of seats under AV and over a hundred under PR. Of course, these are hypothetical results, because we can’t be sure how a different system might change the way electors cast their votes (for the data, see this Grauniad article). All the different systems would still have resulted in a hung parliament, but oddly both AV and PR might have made a Lib-Lab coalition more appealing with a stable majority (mainly because the Lib Dems would have more seats). The ConDems offer of AV is a compromise in that the Tories would possibly lose seats but not as many as under PR, and the Lib Dems would gain seats but not as many as under PR.

22 points about the election

  1. The House of Commons we elect this week will have four more MPs — 650 MPs in total — than the last due to population increase and boundary changes.
  2. This means that the entire UK is divided into 650 constituencies, each will elect one MP.
  3. The average number of registered voters in a constituency is 68,433.
  4. Actual numbers in constituencies can be a few thousand less or more than this. You can check your constituency over at Voter Power Index.
  5. The bigger a constituency the less of a voice one has nationally, as more people than average still get only one MP. The largest constituency is the Isle of Wight with 110,000 registered voters.
  6. The smaller a constituency the more of a voice one has nationally, as fewer people than average still get a full MP. The smallest constituency is Na h-Eileanan an Iar with 22,000 registered voters.
  7. A voting system called First Past The Post is used in each constituency to elect one MP; the candidate with the most votes wins.
  8. This means that often the winner does not receive more than half the votes, with most voters voting for someone else.
  9. Gordon Brown has proposed that a system called Alternative Vote be offered as an option in the future; under AV a candidate would have to secure more than half of valid votes to win.
  10. Neither First Past The Post nor Alternative Vote are proportional electoral systems. That means that if 30% of the electorate vote Conservative, neither system would ensure that 30% of our MPs are Conservatives, as only those who cast a vote for the winner in their constituency affect the composition of the House of Commons.
  11. Continue reading
