The footage of the Duke of York – then the UK's Special Representative for International Trade – was taken less than an hour after Epstein, who had been convicted of sex with a child in 2008, left the house in the company of a young, shivering blonde woman.

The video was shot on December 6, 2010, during a visit by the Prince to Epstein's nine-storey 21,000 square foot mansion dubbed the 'House of Horrors' by many of his young victims.
