Speaking to The Mirror, Mr Page, who worked with the Royals from 1998-2004 said he was first alerted to Maxwell when the privy purse called, informing him that a guest was coming to see Andrew but that the name was not to be entered into the book.

‘She turned up in a chauffeur-driven Range Rover and we let her in. Half an hour after that me and my colleague walked through the garden to go back to the police lodge and he was having a picnic with her by the summer house, opposite the Queen’s ­bedroom window.

‘One of my colleagues saw her come in and out the Palace four times in one day.’

Prince Andrew has been criticised for his relationship with Maxwell and Epstein.
