BRUSSELS ― Belgian police raided the EU’s foreign service and the College of Europe on Tuesday in a bombshell corruption probe — and detained two of the EU’s most powerful officials.

Federica Mogherini, who once served as the EU’s top diplomat, and Stefano Sannino, a director-general in the European Commission, were questioned over allegations of fraud in the establishment of a training academy for diplomats.

Mogherini was born in Rome, the daughter of a film set designer. She was elected to the Italian parliament in 2008 as an MP with the center-left Democratic Party and became Italy’s foreign minister in 2014, an appointment that, at the time, took many by surprise.

The 52-year-old’s tenure was short-lived, as she was made the EU’s high representative — the foreign policy chief — the same year, a position she held until 2019. Her time in the job is perhaps most notable for her work on the 2015 Iran nuclear deal.

At the end of her five-year term, she became the rector of the Bruges-based College of Europe, a position she’s been in ever since. But her appointment was mired in claims of cronyism, as professors and EU officials argued that she was not qualified for the post, did not meet the criteria and applied after the deadline.

She has also served as the director of the EU Diplomatic Academy, a program for junior diplomats across EU countries that is run by the College of Europe, since August 2022.

It’s the academy that is at the center of the probe. The European Public Prosecutor’s Office (EPPO) said it has “strong suspicions” that rules around “fair competition” were breached when the EEAS awarded the tender to set up the academy.

Sannino, a career diplomat from Naples with a packed CV including various roles in Rome and Brussels, has served as director-general of DG Enlargement, permanent representative of Italy to the EU, Italian ambassador to Spain and Andorra and secretary-general of the European External Action Service (EEAS).

He has championed LGBTQ+ rights and is married to Catalan political adviser Santiago Mondragón.

He started his current role as director-general of DG MENA, the EU’s department for the Middle East, North Africa and the Gulf, in February. He has lectured at the College of Europe and at the diplomatic academy.

None of the people questioned has been charged. An investigative judge has 48 hours to decide on further action.
