Papua New Guinea doesn't use the Alternative Vote

We keep hearing the mantra repeated that only three countries in the world use the Alternative Vote - Australia, Fiji and Papua New Guinea. Invariably the focus has been on the first of these three, where data, studies and commentary is most readily available. Of the other two, Fiji has its problems that are rather more deep seated than the voting system, and Papua New Guinea appears misreported.

Papua New Guinea adopted the Alternative Vote in the past but switched to First Past The Post in the mid 1970s. In 2003 they changed the system again, but contrary to much casual reporting they didn't adopt the Alternative Vote.

Instead they adopted the Limited Preferential Vote - see Papua New Guinea Electoral Commission - Limited Preferential Voting for the official description on it.

Now I'm sure many of you are wondering what the difference is. Well under LPV a voter can only indicate preferences for a limited number of candidates. Rounds of transfers follow. A version of this system is actually used in the UK for Mayoral elections, albeit with voters allowed only two choices and the second round involves only the candidates with the two highest first preference totals.

The Limited Preferential Vote displays many of the same issues as the Supplementary Vote and neither of them really qualify as the Alternative Vote. Hardly any AV campaigners in the UK hold up the Supplementary Vote as an example of AV, and the Limited Preferential Vote isn't one either.

So that's two countries that use AV then...
