Controversial tapes of Princess Diana are to be broadcast after her sons spoke publicly about her in a documentary.
The 20th anniversary of the Princess's death falls at the end of August, and Princes William and Harry detailed their memories of their mother in a documentary which aired on ITV on Monday night (July 24).
Now, controversial videotapes made by the Princess and her vocal coach, Peter Settelen, are set to be aired on Channel 4.
The recordings detail Diana discussing her wedding - calling it the "worst day of her life" - the struggles to live up to public pressure, and her sex life with Charles, the Prince of Wales, as well as his affair with Camilla Parker-Bowles.
The tapes were found following a raid on the home of the former royal butler Paul Burrell, and were deemed to be too sensitive for use in his trial in 2002.
They then became the subject of a lengthy legal battle between Settelen and the Spencer family, which was eventually won by the former vocal coach.
Channel 4 says it has informed Kensington Palace of its intention, with the recordings planned to be aired in a contextualised framework.
