Princess Diana was snubbed by Prince Edward in favor of Sarah Ferguson.

In Channel 5’s documentary “Paxman on the Queen's Children,” Prince Charles, Princess Anne, Prince Andrew and Prince Edward’s lives were examined as well as their quality of relationship with their spouses. According to royal correspondent Ingrid Seward, the Earl of Wessex had favoritism when it came to the Princess of Wales and Duchess of York. Prince Edward reportedly preferred Ferguson over Princess Diana.

“He actually used to sometimes have lunch with Fergie who would drive from the Palace and meet him here and take him out to lunch because they were close at one time,” Seward said in the documentary.

When asked by broadcaster Jeremy Paxman why the two were close, Seward attributed it to Ferguson’s fun disposition.

“I think he liked her and she liked him,” she answered. “She was young and fun and she was interested in what he did.”

Aside from not being close with Prince Edward, Princess Diana had a fraught relationship with her sister-in-law Princess Anne, too. At one time, the People’s Princess was heard saying that she would not come to an event if the Princess Royal would also be there.

According to Richard Kay, Princess Anne didn’t like Prince Charles’ first wife. Queen Elizabeth II’s only daughter didn’t like the way Princess Diana went about her duty and how she used the cameras and media to promote herself in their eyes.

Princess Anne didn’t like Ferguson either. According to a previous report, Princess Anne once called Ferguson an "outsider" during a family lunch and this resulted to a furious row. Prince Andrew ordered her royal sister to apologize to his wife. Princess Anne did say sorry but since then their relationship had become “very frosty.”

Princess Diana and Ferguson were very close, they were even believed to be best friends. However, they had a falling-out and were not on talking terms when the People’s Princess died in a fatal car crash.

Princess Diana was also close to Ferguson’s husband, Prince Andrew. The Princess of Wales and Duke of York had a warmer relationship because they had known each other since they were kids. In fact, they played together on the Sandringham Estate.
