Sarah Ferguson may be questioned by police over ex-husband Andrew Mountbatten-Windsor’s arrest, top British legal sources tell Page Six.

Ferguson — who was stripped of her Duchess of York title amid the Jeffrey Epstein scandal — is believed to be in the United Arab Emirates (UAE) after being evicted from her former Royal Lodge home.

However, if and when she returns to the UK, Ferguson, 66, could face questions from the Thames Valley Police, who arrested her ex (aka former Prince Andrew) early Thursday on suspicion of misconduct in public office.

While there is no evidence of any criminal wrongdoing by Ferguson, “The police may have a basis for questioning Sarah Ferguson [as] she may be a relevant witness in this case,” a top barrister told Page Six.

“They may want to ask her some questions. While Sarah Ferguson would not have been in a public office at that time, I don’t know what she knows, and if she has disclosed anything (in emails consistent with her role as an ex-royal and Andrew’s ex-wife).”

The insider added, however, that “it’s up to police” on what they decide to do — “as part of this investigation, they can call upon who they want.”

As Page Six previously reported, Ferguson has always defended Mountbatten-Windsor and given him her support, even after he lost his Prince title.

But she has been left red-faced as a stream of messages released in the tranche of emails in the Epstein Files apparently show her begging the convicted pedophile for cash — and even offering to work for him.

“Just marry me,” she allegedly wrote to Epstein in a January 2010 email, following his release from jail, according to the files.

In a May 2010 email, she requested a job as his “House Assistant,” stating she “desperately” needed the money, and later described herself as “very traumatized and alone,” the files claim.

In 2009, she then asked for £20,000 for rent because a landlord threatened to go to the newspapers.

Following the latest release of Epstein files, six companies that Ferguson was the sole director of are shutting down, according to CNN.

The companies, which include a public relations and communications service firm and a retail business, all reportedly applied to be struck off the UK’s official Companies House register.

Ferguson’s charity, Sarah’s Trust, which focused on improving the lives of women and children, is also closing the “foreseeable future” in the wake of the new Epstein files, according to the AP.

“Our chair Sarah Ferguson and the board of trustees have agreed that with regret the charity will shortly close for the foreseeable future,’’ the trust said in a statement. “This has been under discussion and in train for some months.’’

Andrew was arrested Thursday — which also marked his 66th birthday — on suspicion of misconduct in public office for allegedly forwarding confidential trade documents to Epstein. If convicted, he could face a maximum sentence of life in prison.

Ferguson was believed to be in the UAE at the time the police arrived to arrest the late Queen Elizabeth II’s second son at his temporary home at Sandringham Estate.

Before her trip abroad, the mother of Princess Beatrice and Princess Eugenie was said to have spent a few days with friends in the French Alps ahead of seeking out some winter sun.

A rep for Ferguson declined to comment on Andrew’s arrest.
