Prince William said he "tentatively" welcomes the BBC's new investigation into its controversial 1995 interview with his late mother, Princess Diana. .

The BBC announced last week it is conducting a "robust and independent investigation" into an allegation that Martin Bashir, the reporter who conducted Princess Diana's 1995 bombshell  "Panorama" interview, asked a graphic designer to create fake bank statements to coerce the royal into talking on camera. .

Diana’s brother, Charles Spencer, made renewed claims this month that Bashir used false claims to convince the late royal to agree to the interview.

British station ITV also this month aired a documentary, "The Diana Interview: Revenge of a Princess," featuring interviews that claimed Bashir asked graphic designer Matt Wiessler to create mock bank statements that seemingly proved royal employees were getting paid to spy on Diana

The BBC investigated the Diana "Panorama" interview after it aired and cleared Bashir, 57, of wrongdoing in 1996. A report published earlier this month in The Sunday Times cited 1996 internal BBC documents obtained through the Freedom of Information Act that concluded Bashir was "an honest man" and blamed Wiessler for the episode.
