Once, when Andy Wilson and I wanted to make sure we got to speak in a Marxism meeting - and also because we knew it would have a head-wrecking effect - we came early and sat in the front row, slightly to the right seats that the CC invariably occupied. We had a gentle request to move, I think, but no serious force was applied. And as the CC members came in, it was amusing to see them halt, decide they didn't want to sit next to us and look around for alternatives. It's hard now to capture how defiant this act was and how liberating, because it's hard to remember a time when I was intimidated at the prospect of incurring the wrath of the party apparatus.
