Then US president John F. Kennedy took the virginity of a White House intern in a side room a few feet away from where staffers were drinking at an after-work party, the Daily Mail Sunday quoted a new book as saying.

Mimi Alford, now a 69-year-old grandmother, related how Kennedy led her into "Mrs Kennedy's room" during a personal tour, where he proceeded to have sex with her. The retired New York church administrator's tell-all memoir also details how, during a passionate 18-month affair with Kennedy, he told her to perform a sex act on his friend as he watched.
