“As I leave my office, I think of this famous Danish TV show, Borgen. There is a very famous saying there: 'In Brussels, no one can hear you scream,' and unfortunately, this is true," she said, in a nod to the Ridley Scott blockbuster Alien. "I am concerned that the EPPO is going to be killed softly because it's doing its job."

Kövesi cited three main factors undermining the institution's work: chronic underfunding, delays in the revision of the organization's legal framework and the complexity of its bureaucratic architecture, which she said leads to "endless discussion about how to complicate the life of the prosecutors."

Asked what she would do differently if she could start over again, the chief prosecutor said she “would do the same things, but maybe the others should change their behavior," adding that the biggest challenge her successor, German prosecutor Andrés Ritter, will face is keeping EPPO “independent and credible.”

Kövesi said that during her tenure, “the most blatant attempt" to intimidate EPPO prosecutors was in Greece, which was hit by a farm funding scandal last year — leading to the resignation of ministers and deputy ministers. The cases of four MPs from the ruling New Democracy party are currently being heard in court. They all plead innocent.

Last May, EPPO sent a formal complaint to the Commission regarding moves by the Greek government to block EU prosecutors from investigating Greek lawmakers. It also complained about the Greek Supreme Judicial Council’s refusal to renew the mandate of European-delegated prosecutors for five years at EPPO's request. Kövesi warned that this could result in EU funding cuts for Greece under Article 16 of the EPPO Regulation.

The cooperation between EPPO and the Greek government has been difficult, with Prime Minister Kyriakos Mitsotakis hinting at a political agenda by EPPO by complaining of "selective leaks."
