Wow. I had heard about this but only just watched it.
Here is the video from the event at which Willie Rennie was booed recently. If you watch it, you won’t find it difficult to understand why.
He begins by telling the crowd that the Westminster he thinks we should stay involved in has wasted all Scotland’s money. Then he goes on to scold the socialist movement (quite a few of which seem to be in the crowd) for not being socialist enough (in his idea of socialism anyway), even though he himself, is not exactly a socialist.
This provided the next speaker, Tommy Sheridan with an obvious response, which he utilised to the full.
