Andrew Mountbatten-Windsor remains under investigation by Thames Valley Police for misconduct in public office tied to his former role as UK trade envoy and Epstein links, following his February 2026 arrest and release without charges. No formal charges have been filed more than seven months later, despite expanded inquiries into related allegations and witness appeals. The common-law offense carries a theoretical maximum life sentence but requires proving willful abuse of office to a high threshold, a standard rarely met in practice. Traders assign 98.9% probability to no prison sentence because conviction would demand successful prosecution through the Crown Prosecution Service, a jury trial, and appeals, all of which face substantial evidentiary and institutional hurdles. Late developments such as new corroborated testimony or US-UK evidence sharing could alter timelines, though these remain speculative pending further police updates.
