Under First Past the Post (FPTP), votes are cast for candidates in single member constituencies and whoever gets the most votes (the plurality) wins.

Under AV, voters rank the candidates standing in their constituency in order of preference. If no candidate has more than 50% of first-choice votes, the candidate with the least votes is eliminated, and the second favourite candidates (the “alternative votes”) of all the eliminated votes are added to the tally of remaining candidates; this keeps going until one candidate has more than half the votes.

Would this be a good reform in the UK?
