Diana Photo Mystery Man Revealed

The mystery of the young man sitting beside the late Diana Spencer in a photo apparently prohibited from being published has been solved.
The photo of Lady Diana before she married into the royal family will be up for auction later this month. Besides the identity of the mystery man, the words, "not to be published," written on the image in grease pencil, intrigued the photo's owner, Eric Caren of Caren Archive.
Caren had bought images from the former British newspaper, the Daily Mirror.
The man in the photo is Adam Russell, a student at Oxford University at the time and the great-grandson of former Prime Minister Stanley Baldwin. He is currently a deer farmer in Dorset, England.
Reached on the phone in western England, Russell confirmed with ABC News he was the man in the photo, but refused to say any more.
