A group of friends was enjoying a National party conference dine and dance some years ago when they noticed one of the MPs. He was approaching a table, asking one of the women at it for a dance, doing a couple of circuits of the dance floor with her then walking off and moving on to the next table to invite someone else to dance.
The friends decided when the MP approached their table, which ever woman was invited to dance would accept, start the dance then abandon him before he had a chance to drop her.
The MP approached their table, invited one of the women to dance, she accepted, went part way round the floor, then graciously extricated herself, leaving him by himself looking flummoxed and foolish. Those watching from her table burst in to laughter. The MP heard them and gave them a look which suggested he did not appreciate the joke.
Who was he?
