In commemoration with what's been happening in the Royal Family in the months, let's look back to Princess Diana's time where she did a world-shocking interview to Martin Bashir on Panorama, expressing her failing marriage to Prince Charles. 

How did the Royal Family dealt with the big family issue?

In 1995, Princess Diana did an exclusive interview to BBC's Panorama, which left the world shocked by her revelatiion. Princess Diana was not able to hold back what's really been happening to her and her marriage to the Prince of Wales, Prince Charles. The Princess shared in the interview the "real score" of their marriage, and she shook the whole world when she said there were "three of them in the marriage" and it was a bit crowded. 

How did the Queen and the other members of the Royal Family dealt with the interview after?

The interview with Bashir was made and kept secret from other members of the Royal family. No one knew. 

In the interview, Princess Diana expressed herself about her marriage, admitting her association with army captain James Hewitt. The princess also made reference to her husband's relationship with Camilla Parker Bowles, and her own experience with an eating disorder. 

However, it was reported that the Queen pulled the plug on the BBC's exclusive coverage for her Christmas speech.

In 2006 in the Sunday Telegraph, the BBC exclusives reported that thet had lost their exclusive rights to the Queen's broadcast as a result of the Panorama interview. A memo was made by the publication from the head of events to BBC broadcast's chief executive. The memo indicated that "it is widely perceivied that the BBC is in effect being penalised because of the Princess of Wales' Panorama interview and thus we do not give up our responsibility for the broadcast voluntarily but have to a degree been 'sacked'." 

On the other hand, the Royal Family denied the accusations. 

Members of the Royal Famly were enraged by Princess Diana's actions, including Princess Margaret, who is the Queen's sister. According to biographer Craig Brown, who was also the one who wrote 'Ninety-Nine Glimpses of Princess Margaret', told Fox News that Margaret considers Princess Diana's interview as 'betrayal' to the family. He also stated how Margaret  was very keen at other's misbehaviors and was "very unforgiving". She would not even dare to have magazines with Diana's face on the cover nearby
