Audio and videotapes Princess Diana secretly recorded during her marriage to Prince Charles will get their first public airing next month on American channel NBC.
NBC said it would present excerpts of the audio tapes, the principal source for Andrew Morton's 1992 international bestseller Diana: Her True Story, and separate video footage taken of her during the same period, in a special two-part broadcast set for March 4th and March 11th.
The two-hour documentary, titled Princess Diana: The Secret Tapes, also will feature interviews with some of Diana's closest friends and confidants, NBC said.
An NBC spokeswoman said the video comes from an hour of footage shot by a "professional associate" of Diana's with her permission between September 1992 and December of 1993, a period when details of her troubled marriage had already come to light in Mr Morton's book.
NBC said the footage shows a "relaxed, candid Diana at times laughing and interacting with her young sons, illustrating the lighter side of a woman who maintained a very reserved public persona."
The network said the audiotapes offer an exclusive account, in Diana's own voice, of her life before becoming a princess, her long struggle with bulimia, her suicide attempts, the sadness over her husband's infidelity and her strained relations with other members of the Royal family.
