Overview
- Metropolitan Police detained the 72-year-old at a Camden address and took him to a London station for interview following searches at properties in Camden and Wiltshire.
- The inquiry focuses on 2009 communications that appear to show the then–business secretary sharing internal, potentially market‑moving material with Epstein, with no sexual‑offense allegations.
- Police launched the misconduct probe after the U.S. Department of Justice released new Epstein‑related documents in late January and after Downing Street referred communications to investigators.
- The development follows last week’s arrest of Andrew Mountbatten‑Windsor on suspicion of a similar offense in a separate case; he was released after 11 hours of questioning.
- Mandelson was fired as ambassador in September 2025 and resigned this month from the House of Lords and the Labour Party, while the government plans to publish vetting records in early March.
