The Duke of York’s legal team has hit back at allegations that he provided “zero co-operation” to US authorities investigating convicted sex offender Jeffrey Epstein, instead claiming he has made three offers of help.

America’s Department of Justice (DOJ) has submitted a mutual legal assistance (MLA) request to the Home Office to quiz Andrew as a witness in a criminal investigation into the disgraced financier’s offending.

But in a statement the duke’s legal team said: “The Duke of York has on at least three occasions this year offered his assistance as a witness to the DOJ.

“Unfortunately, the DOJ has reacted to the first two offers by breaching their own confidentiality rules and claiming that the duke has offered zero co-operation. In doing so, they are perhaps seeking publicity rather than accepting the assistance proffered.”

Andrew’s public life was left in tatters after his disastrous Newsnight interview about his friendship with Epstein, which saw him accused of showing little empathy for the financier’s victims.

In the programme’s aftermath the duke stepped back from royal duties but became the focus of US authorities who wanted to question him about the financier, who killed himself in his jail cell while awaiting trial for sex trafficking.

Four days after last year’s interview, the duke said in a statement he was “willing to help any appropriate law enforcement agency with their investigations, if required”.

But Geoffrey Berman, who is leading the Epstein inquiry, told reporters in March: “Contrary to Prince Andrew’s very public offer to co-operate with our investigation into Epstein’s co-conspirators, an offer that was conveyed via press release, Prince Andrew has now completely shut the door on voluntary co-operation and our office is considering its options.”

An MLA request made by foreign countries is a formal process used to obtain help in an investigation or prosecution of criminal offences, generally when co-operation cannot be obtained by law enforcement agencies.

The process is normally secret but with reports on both side of the Atlantic about the request Andrew’s legal team stressed its “commitment to confidentiality” and went on to make accusations of “misleading media briefings” against US prosecutors.

The statement said: “Any pursuit of an application for mutual legal assistance would be disappointing, since the Duke of York is not a target of the DOJ investigation and has recently repeated his willingness to provide a witness statement.

“It is hoped that this third offer has not been the cause of the most recent leak about the Duke of York.”

One of Epstein’s victims Virginia Giuffre, who claims she was trafficked by the financier, also alleges the duke had sex with her on three separate occasions, including when she was 17, still a minor under US law.

The duke categorically denies he had any form of sexual contact or relationship with Ms Giuffre.

The statement said: “It is a matter of regret that the DOJ has seen fit to breach its own rules of confidentiality, not least as they are designed to encourage witness co-operation.

“Far from our client acting above the law, as has been implied by press briefings in the US, he is being treated by a lower standard than might reasonably be expected for any other citizen.”

Andrew’s legal team is made up of Clare Montgomery QC, who represented Chilean dictator Augusto Pinochet, and specialist defence barrister Stephen Ferguson, briefed by criminal defence solicitor Gary Bloxsome from Blackfords.

Their statement stressed the US authorities have been “actively investigating” Mr Epstein for more than 16 years, but their first request for help from the duke was on January 2 this year.

It went on to say: “Importantly, the DOJ advised us that the Duke is not and has never been a ‘target’ of their criminal investigations into Epstein and that they sought his confidential, voluntary cooperation.”

The legal team said they were given an “unequivocal assurance” by the US authorities their discussions and the interview process would remain confidential, but claimed this commitment was broken.

The statement also claimed the comments by Mr Berman, the US Attorney for the Southern District of New York, who said the duke had “shut the door” on voluntary co-operation was “inaccurate”.

Mr Berman’s office declined to comment.
