Since the Labour party leadership debacle I've sometimes wondered if the party knows how many politically hostile people acquired the right to vote in order to elect the most useless candidate. Although the party seems to have a vetting process, I don't think they know.
During my occasional attempts to track down some credible numbers, I came across this article from August 2015. The comments at the end of the piece amused me. There are nine identical comments under nine different names, even though you supposedly have to log in or register to leave a comment. Perhaps someone was making a point.
