This email exchange shows Sarah Ferguson telling Jeffrey Epstein "the British press is ready to exterminate me" during a reported cash-for-access scandal in July 2010.
She calls the disgraced financier her "pillar" and says she has to return to the UK "and be exterminated and face the thunderous music".
"I am now 1,000 percent being hung out to dry, just as I predicted you will see, the Press will have me exiled," she writes.
"I am totally on my own now. This is beyond scandalous and nobody can do anything."
Ferguson then says "no woman has ever left the royal family with her head, and the [sic] cannot behead me, therefore they will discredit me".
The exchange came in the weeks after Ferguson was reported to have accepted $500,000 in return for securing access to her former husband, Andrew Mountbatten-Windsor, who was a UK trade envoy at the time.
In a statement in response to the Epstein files and what they reveal about her close relationship with the sex offender, Ferguson has said: "I would never have anything to do with Jeffrey Epstein ever again. I abhor paedophilia and any sexual abuse of children. It was a gigantic error of judgement."
