British prosecutors have been brought into the investigation into Andrew Mountbatten-Windsor.

Officials from the Crown Prosecution Service are working to provide guidance to police examining 66-year-old former prince’s links to Jeffrey Epstein, who died aged 66 in his New York jail cell in 2019 after apparently taking his own life.

The CPS on Wednesday (local time) confirmed it was offering “early investigative advice” to the Metropolitan Police Service and Thames Valley Police as inquiries continue into Mountbatten-Windsor’s conduct.

Mountbatten-Windsor was arrested in February on his 66th birthday on suspicion of misconduct in public office. He was released after some hours but is still being investigated over allegations he shared commercially sensitive information with Epstein while serving as a British special trade envoy between 2001 and 2011.

Police are also examining separate allegations a woman was trafficked to Britain by Epstein to have a sexual encounter with the former prince.

The CPS is also advising police in a related investigation involving politician Peter Mandelson, 72, who was arrested on suspicion of the same offence.

“We can confirm that we are now providing early investigative advice to the Metropolitan Police Service regarding the force’s investigation into a 72-year-old man and will continue to liaise as requested,” a spokesperson for the Crown Prosecution Service said.

“We can now also confirm that we are providing early investigative advice to Thames Valley Police in relation to a 66-year-old man.”

The spokesperson said service remained “ready to support any investigation if needed”.

The CPS provides guidance to British police during investigations, including advice on evidence gathering and whether a case meets the threshold for charge.

Prosecutors will consider whether there is a “realistic prospect of conviction” before proceeding.

Mountbatten-Windsor was photographed in the back of a car following nearly 12 hours of police questioning after his arrest. He has largely been out of the public eye since.

Officers later carried searched Wood Farm, his temporary residence at the time, and his former home at Royal Lodge. Devices were seized as part of the investigation.

The actions followed the release of extensive files linked to Epstein.

Mountbatten-Windsor has denied wrongdoing.
