On May 3, 2007, Scottish voters used two proportional voting systems simultaneously: for the first time ever, choice voting (or the single transferable vote) for local councils, and once again, mixed member proportional voting for the Scottish Parliament. The local council elections saw increased participation and broadly representative results. Despite the first-time use of choice voting alongside a completely different voting system, error rates were, on average, remarkably low. The MMP elections ensured proportionality in seat shares and arguably prevented a wrong-winner result. There was early controversy over error rates allegedly around 10%, but actual error rates were lower. Later research moreover confirmed that voter error was due to critical ballot design flaws.
