It has been claimed that Andrew would instruct staff members to simply let her in and show her the way to his rooms. The women would reportedly always enter via a staff entrance.

It has been claimed by a former member of staff that this went on “for years”, as reported by Tom Sykes, and that Andrew would use the code word “Mrs Windsor”.

Speaking to The Sun, the source said: “It was common knowledge that Andrew liked to have young women visit Buckingham Palace.

“He would phone the duty office and always say the same thing – ‘Mrs Windsor will be arriving shortly – please let her in and show her up’.

“This was always via one of the out-of-sight staff entrances.

“It was so frequent that they used to just roll their eyes and say ‘yes sir’. It went on for years. The royal protection officers hated being assigned Andrew as he was so unpleasant and dismissive.”

It is believed this is because Andrew was high up in the Royal Family, especially as he was Queen Elizabeth II’s son.
