Sarah Ferguson has not been seen publicly for months.
But while rumours swirl about the former duchess’s whereabouts and whether she is contemplating a tell-all interview, there are mounting calls for her to give evidence concerning her links to Jeffrey Epstein.
US lawmakers have repeatedly called for her former husband, Andrew Mountbatten-Windsor, to answer questions about his links to the late American financier and sex offender. Now Ferguson is being urged to do the same.
Congressman Suhas Subramanyam, a member of the House Oversight Committee investigating the handling of Epstein’s prosecution, said he now believed she had “information related to the investigation”.
“Sarah Ferguson should give sworn testimony to our committee,” he said.
There is no legal mechanism to compel Ferguson to testify in the US.
But Subramanyam told the BBC that lawmakers would be “happy to work out terms that work for her”, as long as she was under oath.
Ferguson’s representatives declined to comment.
Subramanyam’s calls were echoed by Democratic Congresswoman Melanie Stansbury, who urged anyone with information of wrongdoing by Epstein and his associates to cooperate in order to ensure justice for the survivors.
“If Ferguson or any member of their family has such information, our responsibility is to follow the facts wherever they lead,” she told the BBC.
The family of prominent Epstein accuser Virginia Giuffre also said they “strongly believed” the former Duchess of York should go to the US to answer questions.
“If Ferguson knows anything, she should testify in the United States immediately,” a representative for Giuffre’s brother Sky Roberts told the BBC.
