ABC's 'The Story of Diana' special to feature Charles Spencer interview

July 1 (UPI) -- Charles Spencer, the brother of the late Princess Diana, will appear in ABC's two-night television program The Story of Diana.

Scheduled to air Aug. 9-10, the four-hour special will also feature interviews with Richard Branson, Jess Cagle, India Hicks, Lana Marks, Elizabeth Vargas and others.

"On the eve of Princess Diana's birthday, ABC and Time Inc.'s People announce the list of exceptional voices to be featured in The Story of Diana," a press release said. "Charles, 9th Earl Spencer, brother of the late Diana, Princess of Wales, gives his exclusive U.S. interview, providing personal and touching stories of his beloved older sister set to archival and home movie footage of Diana from her childhood through her adult life. This rare opportunity to hear from someone so close to the 'the People's Princess' will share an intimate glimpse into her remarkable, yet far-too-short life."

Diana, who was married to Britain's Prince Charles from 1981 to 1996, died from injuries sustained in a Paris car wreck on Aug. 31, 1997. She would have turned 56 Saturday.
