British newspaper the Sun says that Andrew is funding the renewed effort in part with his inheritance from his mother, the queen, who died in September.

A royal source told the Sun: “Andrew was pressured into settling the case to avoid overshadowing the Platinum Jubilee and has paid a heavy price, personally and professionally.

The terms of the settlement have remained secret, but it has been widely reported he paid around $14 million to settle with Giuffre but made no admission of guilt.

Andrew has always claimed, privately, that the photo is fake and while he has not been so explicit in public statements, he strongly implied as much to Emily Maitlis in a disastrous BBC Newsnight interview.

The photo was lost after apparently being stuffed into one of several storage boxes and shipped from Colorado to Sydney when Giuffre move to Australia, at some point between 2011 and 2016.

“Copying” a photograph by taking a photo of it is a standard news-gathering technique to obtain an image without requiring the owner to relinquish the original.
