Edward Heath
His interest in music kept him on friendly terms with a number of female musicians including Moura Lympany. Lympany had thought Heath would marry her, but when asked about the most intimate thing he had done, replied, "He put his arm around my shoulder." Bernard Levin wrote at the time in The Observer, forgetting two other prime ministers who were bachelors with no known romantic interests, that the UK had to wait until the emergence of the permissive society for a prime minister who was a virgin. In later life, according to his official biographer Philip Ziegler, Heath was "apt to relapse into morose silence or completely ignore the woman next to him and talk across her to the nearest man".
