A US lawmaker has made a direct plea to Sarah Ferguson to testify about her close personal and business ties to Jeffrey Epstein, according to a letter seen exclusively by the BBC. Congressman Suhas Subramanyam urged her to provide information to the US congressional committee investigating the late sex offender. He also asked for any knowledge she had of her ex-husband Andrew Mountbatten-Windsor's involvement in Epstein's operations.

The letter represents the most direct pressure on the former duchess to testify since the start of the Epstein scandal. Ferguson's representatives have been approached for comment. Mountbatten-Windsor has denied any wrongdoing in relation to Epstein.

Subramanyam's letter, sent on Thursday and setting a two-week deadline for her response, revealed Ferguson’s close personal and business ties with Epstein, as recent files released by the US Department of Justice shed new light on her relationship with him. He wrote, As the committee seeks justice for the survivors of Mr. Epstein's criminal enterprise, and transparency for the American public, I respectfully request your cooperation with the committee's investigation.

Among the details mentioned, the letter referenced past emails from Ferguson describing Epstein as a legend shortly after his 2008 conviction for soliciting prostitution from a minor. It also highlighted her requests for financial assistance directly from Epstein.

The committee expressed interest in learning about any possible involvement by Mountbatten-Windsor, who has also faced calls to provide testimony regarding his links to Epstein. While being named in the Epstein files does not imply wrongdoing, the connection has resulted in Ferguson losing her duchess title and facing pressure from the public and the families of Epstein’s accusers to come forward with information about her associations with him.
