During Prince Andrew's Newsnight interview, he was asked whether he slept with Virginia on the New York trip:
"I think that the date we have for that [the New York encounter] shows that I was in Boston or I was in New York the previous day and I was at a dinner for The Outward Bound Trust in New York;
"Then I flew up to Boston the following day and then on the day that she says that this occurred, they'd already left to go to the island before I got back from Boston. So I don't think that could have happened at all."
The Telegraph's source said it was impossible to pinpoint his movements on the trip as it had taken place 'a long time ago.' The aide also defended the Duke, saying he wouldn't have slept with Roberts.
"The Duke is absolutely not capable of this. Epstein is clearly horrible but I'm confident (of the Duke's innocence). It's inconceivable," the aide said.
"The Duke's words in his interview speak for themselves," a spokesman for Buckingham Palace told MailOnline.
"It is emphatically denied that The Duke of York had any form of sexual contact or relationship with Virginia Roberts. Any claim to the contrary is false and without foundation."
Prince Andrew's trainwreck British TV interview about his involvement in the Epstein sex scandal has been widely criticised.
As a result, the Duke announced he will step back from public life, saying his association with convicted pedophile Jeffrey Epstein is 'a major disruption' to the Royal Family.
