A royal insider is dismissing the claims of Shukri Walker, a new witness in the sex scandal involving Prince Andrew and Virginia Giuffre. The insider said that it's "difficult to believe" that the woman could still remember events from 2001 with clarity.

Speaking with Daily Mail, the royal insider questions Walker's "razor sharp recollections" of what happened almost 20 years ago. Walker said that she saw Prince Andrew with Giuffre at the Mayfair club in London on the night Giuffre said she was forced to have sex with the Duke of York.

Walker revealed that Prince Andrew stepped on her foot on the dance floor and then apologized to her. She also recalled seeing the royal chat and dance with Giuffre when the Duke of York said he was at Pizza Express with Princess Beatrice, and not with the victim, on March 10, 2001. 

The witness claimed that she decided to come forward and speak out after she watched Prince Andrew deny meeting Giuffre on television. Giuffre was only 17 years old when she worked as Jeffrey Epstein's sex slave and claimed to have been with Epstein's pal, Prince Andrew, three times. 

Walker is now in touch with Giuffre's lawyer, Lisa Bloom, and they passed her testimony to the FBI, which is seeking to talk with the Duke of York about Epstein's sex trafficking case. The witness also said that Prince Andrew and Giuffre were with Epstein and Ghislaine Maxwell on that same night. 

She said that she would never forget this because it was the first time she had seen a real prince in the flesh. Her companion told her he was Queen Elizabeth's son. 

Meanwhile, Giuffre said in a recently unsealed court document that Prince Andrew groped her and other young women using a kinky latex puppet of his image and likeness. The puppet was allegedly a gift from Maxwell, and Giuffre detailed that the groping happened in Epstein's New York home. 

The victim said that she was with another girl, Johanna Sjoberg, when Prince Andrew "played" with them in the "House of Horrors" – their codename for Epstein's New York mansion. After the groping, Giuffre indulged Prince Andrew with an erotic massage. 

The revelations were part of a 2016 defamation deposition Giuffre filed against Maxwell. A New York judge ordered these documents unsealed for the current criminal case against Maxwell's sex trafficking activities.

The prosecution has been trying to link Prince Andrew to Maxwell and Epstein's illegal activities, but his lawyers are preventing an extradition to the U.S.

Buckingham Palace has not made any comments about these latest revelations.
