On 16 July 2025, the Commission adopted the decision confirming Sweden's participation in the European Public Prosecutor's Office (EPPO). The EPPO will be operational in Sweden 20 days after the appointment of the European Prosecutor from Sweden, which is expected in autumn 2024. Sweden had formally notified the Commission of its intention to join the European Public Prosecutor's Office on 5 June 2024.

On 29 February 2024, the Commission formally confirmed Poland's participation in the enhanced cooperation scheme of the EPPO. Hence, by the end of 2024, the EPPO will be able to investigate and prosecute fraud affecting Union funds in 24 EU countries. At this stage, only Denmark, Ireland, and Hungary do not participate in the EPPO.
