Princess Diana may have been the people’s princess but behind palace walls, she didn’t receive any support from Prince Charles and the rest of the royal family.

Although Diana was often praised for the kindness she showed to commoners while carrying out her royal duties, a new interview from her former friend revealed the Princess of Wales’ in-laws looked down on her warm gestures.

In the Channel 5 “Paxman on the Queen’s Children” documentary, Daily Mail editor Richard Kay revealed Princess Diana brought humanity to the public perception of the royal family.

“The only one who had brought it down to a human level was Diana. And she had been mocked, roundly mocked, by her husband’s family,” he explained.

Kay noted the royal family had a stuffy public imagine that needed to change. “They really had to do something to address the popularity, not just of the Prince of Wales, which was absolutely on the floor, but also the whole approach to monarchy. It was still rather distant,” he said.

At Princess Diana’s funeral, former royal press secretary Dickie Arbiter admitted he had to force Prince Edward to mingle with the crowd and sign the book of condolence.

“I said, ‘I want you to go this morning, and this morning you will go.’ I was telling a member of the Royal Family what to do. I was pretty fed up by then.”

After Prince Charles and Princess Diana finalized their divorce in 1996, she died in a car crash the following year.
