I am sure you are right, he may have never said it . Bu t liked the thought myself.Complete Codswallop!
Winston Churchill first held a public office when he was 26 years old and after military service. He didn't become prime minister until he was 65.
He left public service when he was 76 but lived until age 90! I can assure you that everyone cared about what Churchill thought right up until the end of his life.
