Former prince. And t's not purposefully vague, the article explicitly says "It comes after Thames Valley Police said they were assessing a complaint over the alleged sharing of confidential material by the former prince with late sex offender Jeffrey Epstein"
If you read through the BBC post, it alludes to passing confidential trade documents to Epstein... but of course that's probably because he was being blackmailed by Epstein for f*cking under age girls.
