Peter Mandelson is being investigated by the EU’s anti-fraud agency over his time as the bloc’s trade commissioner.The European Anti-Fraud Office (OLAF) confirmed on Friday that it had begun an inquiry into Britain’s former US ambassador, who was sacked from his post last year over his links to paedophile Jeffrey Epstein last year.It comes two months after the European Commission asked the agency to look into Lord Mandelson after further information about his ties to the disgraced financier emerged."OLAF ‌can confirm the opening of an ‌investigation on the case ‌that you refer to. However, ⁠as the investigation is ongoing, OLAF cannot issue any further comment," it said via email on Friday.Mandelson served as the European Commissioner for Trade between 2004 and 2008, before he resigned to join Gordon Brown’s cabinet as business secretary (PA Wire)Lord Mandelson served as the European Commissioner for Trade between 2004 and 2008, before he resigned to join Gordon Brown’s cabinet as Business Secretary.Separately, police in the UK are investigating Lord Mandelson’s contact with Epstein during his time in Mr Brown’s government, after documents released in the Epstein files appeared to show him sharing market-sensitive emails with the disgraced financier.Lord Mandelson's ‌legal representatives did ​not immediately respond ‌to a ⁠request for ⁠comment. The news of the latest probe comes after the European Commission asked OLAF to open an inquiry into the former Labour peer’s time as trade commissioner in the wake of the release of the Epstein files in February.Mandelson appeared to confirm a yet-to-be-announced €500bn bailout of the Euro in emails between himself and Epstein during his time as the UK’s business secretary (PA)A spokesperson for the commission said at the time: “Whenever there is any indication of a possible breach of the obligations under the (code of conduct), the commission assesses these possible breaches and takes action on that basis, if necessary.“On this basis, and as new documents were published recently, we are looking into these and assessing whether there is any breach of the respective obligations.”Meanwhile, Sir Keir Starmer has been facing yet more questions at home over his decision to appoint Lord Mandelson as Britain’s ambassador to the US.Outrage over the appointment was renewed last week when it emerged Foreign Office officials had granted the former Labour peer developed vetting status, allowing him to take up the role – despite UK Security Vetting (UKSV) advising against doing so.The crisis has piled pressure onto the prime minister to resign, with some Labour backbenchers publicly calling on him to step down.
