Mandelson was the EU's Trade Commissioner from 2004–08, when the UK was still a member of the Union.
The Commission in Brussels has requested that the European Anti-Fraud Office (OLAF), which investigates corruption, probe Mandelson, an anonymous spokesperson told AP.
Lord Peter Mandelson, who has held several ministerial posts in Labour-led governments, was fired as ambassador to the United States when the extent of his contacts with Jeffrey Epstein was revealed.
In the UK, there is an investigation into whether Mandelson abused his office in any way in connection with his relationship with Epstein. His relationship with Epstein also continued during Mandelson's time in the European Commission.
