King Charles has said he is ready to support British police as they assess allegations that his brother, Prince Andrew, shared confidential information with the late sex offender Jeffrey Epstein while serving as a UK trade envoy.

The claims emerged following the release of new Epstein-related files by the United States Department of Justice, which appear to show that Andrew Mountbatten-Windsor sent confidential material to Epstein in 2010.

Graham Smith, chief executive of the British anti-monarchist group Republic, said he reported Mountbatten-Windsor to the police for “suspected misconduct in public office and breach of official secrets.”

Thames Valley Police confirmed receiving the report, saying, “We can confirm receipt of this report and are assessing the information in line with our established procedures.”

Buckingham Palace said the monarch has shown “profound concern” over the allegations and would cooperate if approached by investigators.

“While the specific claims in question are for Mr Mountbatten-Windsor to address, if we are approached by Thames Valley Police we stand ready to support them as you would expect,” a palace spokesperson said.

Mountbatten-Windsor has previously denied any wrongdoing relating to his association with Epstein and has not publicly responded to the latest allegations.

The renewed scrutiny comes amid wider fallout from the release of the Epstein files. Former UK ambassador to the United States, Peter Mandelson, recently stepped down from the House of Lords after documents appeared to suggest he shared sensitive government information with Epstein following the 2008 financial crisis.

British police have since carried out raids on properties linked to Mandelson as part of an investigation into alleged misconduct in public office.

Prince Andrew served as a UK trade envoy from 2001 until stepping down in 2011 after sustained criticism over his ties to Epstein. Emails cited in the latest files show Epstein requested details of an Asia trip by the former prince in 2010, to which Mountbatten-Windsor allegedly responded by sharing an itinerary covering Vietnam, Singapore and Hong Kong.

After the trip, he is said to have forwarded visit reports to Epstein that were originally prepared by his then special adviser.

Although trade envoys are not civil servants, official parliamentary records state that the role carries a duty of confidentiality, including after leaving office, and may cover sensitive commercial or political information.

In a 2019 interview, Mountbatten-Windsor said he met Epstein in New York in 2010 solely to end their relationship.

“I went there with the sole purpose of saying to him that because he had been convicted, it was inappropriate for us to be seen together,” he said.

Further emails cited in the documents suggest Mountbatten-Windsor later sent Epstein what he described as a “confidential brief” related to investment opportunities in Afghanistan’s Helmand province.

The latest developments come shortly after the former prince moved out of his longtime Windsor residence amid the ongoing Epstein controversy. A spokesperson for the Prince and Princess of Wales said they were “deeply concerned” by the newly released documents and stressed that “their thoughts remain focused on the victims.”
