The European Union has initiated a sweeping investigation into Peter Mandelson, former EU Trade Commissioner and British ambassador, following revelations about his alleged connections to convicted sex offender Jeffrey Epstein. The inquiry, announced on February 26-27, 2026, is being led by the European Anti-Fraud Office (OLAF) and comes after the release of documents by the US Department of Justice. Authorities in both Brussels and the UK are examining whether Mandelson engaged in misconduct, including the sharing of sensitive information and potential breaches of the European Commission’s code of conduct during his tenure from 2004 to 2008.

The probe centers on Mandelson’s alleged contacts with Jeffrey Epstein during his time as EU Trade Commissioner and UK ambassador. Investigators are scrutinizing claims that Mandelson had prior knowledge of a €500 billion rescue plan in 2010 and may have leaked confidential details to Epstein. The European Commission formally referred the case to OLAF, and UK authorities have launched a parallel criminal investigation into Mandelson’s conduct. Huanqiu+2
Recent disclosures include documents suggesting Mandelson’s involvement in sharing sensitive EU information with Epstein. The US Department of Justice’s release of the so-called “Epstein files” prompted renewed scrutiny and media attention. Authorities are also reviewing Mandelson’s compliance with the European Commission’s code of conduct and whether his actions constituted a breach of trust or abuse of office. The Independent+2
The case has triggered significant concern within EU institutions and the UK government. Keir Starmer, UK Labour leader, has stated he will not intervene in the release of Mandelson’s official papers. The European Commission emphasized the importance of transparency and accountability, while OLAF’s investigation is expected to set a precedent for handling high-profile misconduct cases involving senior officials.
