I do not See Squeamish' post implying that at all. There have been plenty of left wing parties over the years. I even voted for one - Colin Fox of the SSP - me and 166 of my fellow citizens. They never get into power and they never last long. Because of that, periodically philosophical (as opposed to practical) socialists infiltrate the Labour Party in the hope of gaining power that way. All that happens is they drive votes away from the Labour party and hand the Tories a free pass to power.
