The plan was to give sex hormones to Hitler and counterbalance his unnecessary aggression.
The British government planned to turn Adolf Hitler into a woman.
The strange move has been revealed in a book by Professor Brian Ford, a fellow at Cardiff University and pioneer of popular science, who explained ministers wanted to smuggle female sex hormones into the evil dictator's food in an attempt to turn him into a woman and therefore make him "less aggressive".
Brian explained: "There was an allied plan that they would smuggle oestrogen into Hitler's food and change his sex so he would become more feminine and less aggressive.
"Their research had showed the importance of sex hormones - they were beginning to be used in sex therapy in London.
