It was a bombshell TV interview the palace didn’t see coming. An estranged royal determined to set the record straight made sensational allegations about how she was treated by the family, especially while she was dealing with mental health issues. The institution of the royal family itself came under fierce scrutiny, and questions were raised by the media about whether the Queen’s heir would end up taking the throne. The BBC’s interview with Princess Diana in 1995 was a milestone in the media’s relationship with the palace.
