Well worth listening to this frank 15 minute Radio 4 interview with Stuart Christie “In 1964 a young Scot called Stuart Christie joined a plot to assassinate the Spanish dictator General Francisco Franco. He had become friends with Spanish exiles living in London and was keen to help end Franco’s rule. But the plot failed and Christie ended up in jail. He has been telling his story to Mike Lanchin. ” BBC Radio 4

Thanks to Christine of stillcause for flagging this.
