Sarah ‒ affectionately referred to as Fergie ‒ was turned down as a prospective lady-in-waiting for Diana, because she was deemed “most unsuitable”. Sarah Bradford, Viscountess Bangor, told the Daily Mail last year that the Princess of Wales was furious about this. She said: “I always felt Diana was wary of Fergie and yet when Fergie was turned down as a prospective lady-in-waiting for Diana because she was deemed ‘most unsuitable’, Diana was furious.”
The Viscountess added that the pair used to get up to all sorts of mischief together and recalled one particularly raucous night for the young royals.
It was Fergie’s hen night before marrying Prince Andrew in 1986.
She and Diana apparently wore grey wigs, dressed up as police officers and pretended to arrest a “prostitute” outside Buckingham Palace.
Their antics even led to them being picked up by the police.

Ms Bradford said: “They were put in a police van and driven down The Mall until one of the policemen recognised Diana.
“He was so shocked he couldn’t believe it and said, ‘Oh my heavens, it’s the Princess of Wales!’”
Later in the night, Fergie and Diana went to Annabel’s nightclub where they narrowly missed Andrew.
Then, when they got back to Buckingham Palace, they succeeded in tricking the police officers on the gates at Buckingham Palace and they shut the gates in Andrew’s face as his car approached.

Unfortunately, this spooked Andrew and, fearing an ambush, he shot into reverse.
Ms Bradford added: “That’s when Fergie wondered if she’d gone too far.”
The idea that Diana and Fergie were always up to mischief together was backed up by other royal commentators, including former BBC
