A letter written by Princess Diana has surfaced, revealing her motivations for participating in the explosive 1995 interview with journalist Martin Bashir. In the two-page letter, dated November 27, 1995, Diana expressed her desire for her sons, Princes William and Harry, to understand the importance of deep communication. The letter was a response to a viewer, Michael Barratt, who had sent her a supportive message after the interview, which attracted 23 million viewers. Diana hoped the BBC Panorama program would resonate with women facing similar struggles. The letter, currently held by Barratt, is expected to fetch between £3,000 and £4,000 at auction. Additionally, the auction features a Madame Tussauds sittings sheet for Diana, which provides insights into her styling and is estimated to sell for £500 to £1,000. The interview itself has been scrutinized due to revelations of deception by Bashir, which ultimately impacted Diana's relationship with William, who was deeply affected after watching it.
