Andrew Mountbatten-Windsor remains under investigation for misconduct in public office tied to his time as UK trade envoy, but no charges have been filed since his February 2026 arrest linked to Jeffrey Epstein documents. A recent High Court ruling quashed the search warrants on procedural grounds, creating evidentiary hurdles for Thames Valley Police while leaving the probe formally open ahead of further proceedings in 2027. The common-law offense carries a maximum life sentence yet requires proof of willful abuse of public office, a high threshold with limited precedent in comparable cases. Traders assign 97.3% probability to no prison sentence because charging decisions rest with the Crown Prosecution Service and face significant legal and evidentiary barriers. Late developments such as new admissible evidence or a charging decision could still shift outcomes before any trial.
