She has investigated a variety of issues from asbestos on state-owned train infrastructure and abuses of election campaign law, to Slovenia’s own anabolic steroid king Mihael Karner.
At the end of 2011 she uncovered that leaders of the Slovenian branch of worldwide neo-Nazi organization Blood&Honor were actively involved in the ranks of leading right-wing party. As a direct consequence of her articles, Delić was charged with publishing classified information, charges that were dramatically dropped by state prosecutors minutes before judgement. Subsequently, the Slovenian government changed the article of Criminal Code relating to publication of state secrets.
In 2015 she started The MEPs Project. She gathered journalists representing all 28 EU Member States who filed requests for access to documents of the European Parliament that show how Members of the European Parliament (MEPs) spend the professional allowances they receive on top of their paychecks. Journalists were refused access, and thus filed complaints against the European Parliament with the European Court of Justice. Cases are pending. The group launched its first investigation in May 2017, which revealed how some MEPs abused their allowance, and includes a search facility for readers to check the filings of their local MEP.
In 2015 and 2016 Delić – also a partner of OCCRP – worked on ICIJ’s Panama Papers investigation which brought her and more than ten colleagues at Delo the highest journalistic award in Slovenia: the Slovene Association of Journalists’ Watchdog Award for Extraordinary Achievements.
