Bluntly, if you seriously think the BBC—which has been on an anti-left crusade for the past decade—has a "left wing bias", that Wikipedia's accuracy is "high", or that the Communist Party has no left-wing bias(!), you really don't understand how to assess either reliability or neutrality in Wikipedia terms. There is absolutely no possibility that we're going to accept this obviously bullshit user-generated site as a reliable source for anything.
