Stripped of his royal titles, Andrew Mountbatten-Windsor, the former Prince Andrew, is being investigated by the British police over accusations that he shared confidential documents with Jeffrey Epstein, the financier and convicted sex offender who died in 2019.

Mr. Mountbatten-Windsor was briefly arrested in February, but he has not been charged with a crime and denies wrongdoing.

The information he has been accused of sharing with Mr. Epstein relates to his work as a British trade envoy, a post he held between 2001 and 2011. After pressure from lawmakers in the opposition Liberal Democratic Party, some official records about his appointment to that position were released on Thursday.

Here are five things we learned from the documents.

Queen Elizabeth II wanted him to have the job.

There has been speculation about who lobbied for Mr. Mountbatten-Windsor to get the trade envoy position, and whether they might have included another friend of Mr. Epstein, Peter Mandelson, a former cabinet minister. Mr. Mandelson was fired last year as Britain’s ambassador to the United States over his links to the disgraced financier, and the repercussions from his appointment have dogged Prime Minister Keir Starmer’s government.

The documents released on Thursday do not suggest that Mr. Mandelson was involved in getting Mr. Mountbatten-Windsor the post, or that any lobbying was needed. One paper, from 2000 — recounting discussions within the government about what would happen when the envoy role was vacated by another member of the royal family, the Duke of Kent — shows that Mr. Mountbatten-Windsor had an extremely well-placed advocate.

“The Queen’s wish is that the Duke of Kent should be succeeded in this role by the Duke of York,” the document reads, referring to Mr. Mountbatten-Windsor by a title he held at the time. It added: “The Queen is very keen that the Duke of York should take on a prominent role in the promotion of national interests.”
