An investigation found that Frontex was complicit in Greek efforts to force migrants and asylum-seekers crossing the Aegean Sea to return to Türkiye hiding Greece's illegal actions.
Europe's border agency Frontex has routinely covered up illegal "pushbacks" of migrants by the Greek coastguard, media reports said, citing a leaked internal review.
A 129-page investigation by the European Anti-Fraud Office (OLAF) found that Frontex, under former executive director Fabrice Leggeri, was complicit in Greek efforts to force migrants and asylum-seekers crossing the Aegean Sea to return to Türkiye, German magazine Der Spiegel wrote on Thursday.
The confidential report was also seen by France's Le Monde newspaper and investigative outfit Lighthouse Reports. It follows repeated allegations by aid groups that Frontex was turning a blind eye to Greek human rights violations at sea.
"Instead of preventing the pushbacks, Leggeri and his people covered them up. They lied to the EU Parliament and concealed the fact that the agency even supported some pushbacks with European taxpayers' money," Spiegel wrote.
The OLAF review found that at least six pushback incidents involved Greek coastguard ships that had been co-financed by Frontex, the magazine said.
Air patrolling stopped
In one incident in August 2020, Frontex Surveillance Aircraft filmed Greek coastguard towing a dinghy with around 30 migrants on board towards Turkish waters – when they should have been taken to Greece.
Instead of confronting Greek authorities, Frontex stopped patrolling the Aegean by air, saying the planes were needed elsewhere, Spiegel wrote.
A hand-written note found later by OLAF investigators said that Frontex management withdrew the aircraft "so as not to become a witness" to Greece's illegal actions.
The Greek government has consistently denied the allegations of pushbacks.
The OLAF investigation paints a damning picture of Leggeri's leadership, Spiegel said, adding that the report's revelations played a role in his resignation last April.
Responding to the OLAF report leak, a European Commission spokeswoman said "a set of measures" had already been introduced "to address the governance issue of Frontex", which has been headed by interim executive director Aija Kalnaja since the start of July.
"In terms of our work with the Greek authorities, there is progress also on the ground," Anitta Hipper told reporters, pointing to a new legislative proposal "to ensure that there is a robust monitoring system" for arriving migrants.
Former boss Leggeri's seven years as Frontex chief, marked by repeated political scares over migrant arrivals in Europe, coincided with a major increase in resources for the agency.
Frontex is set to grow to 10,000 staff watching the EU's external borders by 2027.
