The EPPO, which Hungary has so far refused to join, investigates crimes affecting the EU budget, including fraud and corruption. Magyar has framed the step as part of a broader anti-corruption push aimed at restoring trust in state institutions after 16 years of Fidesz rule. The promise is also politically significant because Budapest has billions of euros in EU funding suspended over rule-of-law concerns. But joining the EPPO alone would not automatically release the money, which Brussels has tied to a wider package of reforms.
