The identity of the man was never revealed and simply become known as the “headless man” as he could only be seen from the neck down.
Over the years, there have been several high-profile names linked to being the potential lover of the Duchess.
Some of the names include a member of the royal family, Lord Beaverbrook’s heir Max Aitken, and the secretary of state for the Commonwealth at the time, Winston Churchill’s son-in-law Duncan Sandys.
It was later revealed many of the men the Duke had accused his wife of cheating on him with were gay.
