Sarah Ferguson joined the royal family when she married Queen Elizabeth’s son Prince Andrew in 1986.
However, there was one member of ‘The Firm’ who was never a fan of the Duchess.

Fergie was always considered a ‘controversial royal’ and by the time she and Andrew divorced in 1996, she had been largely ousted.
While royals such as Prince Philip were known to find the Duchess distasteful, it was also common knowledge that royal rebel Princess Margret disliked her.
In the 1997 documentary Fergie: Downfall of a Duchess royal correspondent Judy Wade revealed a “cruelly unfair” moment when the Queen’s sister rebuked Fergie.
The pair had initially been friendly, however their relationship had soured, Ms Wade explained in the YouTube documentary.
Ms Wade commented: “I thought that was the worst example of a pot calling the kettle black in history.”
She added: “Princess Margaret was notorious for her behaviour.”
“It was totally out of keeping with her position.”
Margaret had a controversial life herself.
She caused a sensation in the 1950s because of her romance with with Group Captain Peter Townsend.
The princess could not marry the older, divorced Townsend without giving up her royal position – and eventually chose her royal duty over the love of her life.
Throughout her younger decades the princess was also known for her party-girl lifestyle.
Ms Wade continued: “Margaret was cruelly unfair to do such a thing when it was a kind gesture from Sarah.
“I think that indicates exactly how the royal family treats someone who steps out of line – except if they’re born royal.”
