I am grateful to the Society for the opportunity to mark the centenary of the Enabling Act and the beginning of the Church Assembly with some reflection on an often ignored but highly valuable feature of that inauguration: the Single Transferable Vote or STV. I tried on one respected registrar recently an illustration of what the task must be like for those who do not welcome it. Was it, I suggested, like a blind person doing a jigsaw where the pieces were all shaped differently from each other – in other words, where the blind person could ensure that it was put together accurately, but on the other hand never saw the picture? The response was that that picture reflected accurately how it had in fact felt to that registrar. That might suggest that this lecture should be explaining and commending STV as general good practice, but in the event the process and virtues of STV have here to be largely taken for granted. I offer here one short commendation of STV.
