March 2010, etc. and studies regarding Eurojust, provided valuable input. National and European Parliaments In November 2013 the Commission concluded that the establishment of a European Public Prosecutor's Office complied "with the principle of subsidiarity" in a report addressing the issue, after it was raised by 14 national parliamentary chambers in 11 Member States. The European Parliament subsequently voted in favour of the commission's proposal to set up the body. On 23 September 2019, the European Parliament and the Council of the European Union agreed on appointing Laura Codruța Kövesi as European Chief Prosecutor. Role and structure The role of the EPPO is to investigate and prosecute fraud against the budget of the European Union and other crimes against the EU's financial interests including fraud concerning EU funds of over €10,000 and cross-border VAT fraud cases involving damages above €10 million. Previously, only state authorities could investigate and prosecute these crimes and could not act beyond their borders. OLAF, Eurojust and Europol similarly had no ability to act. The body is intended to be decentralised, based around European Delegated Prosecutors located in each participating Member State. The central office consists of a European Chief Prosecutor supported by 22 European Prosecutors, as well as technical and investigatory staff. The EPPO may request a suspect's arrest, but this must be confirmed by the relevant state authority. The EPPO has a two-tired structure and is described as a hybrid set-up. The European Chief Prosecutor heads the EPPO, represents it externally, and presides over its college. Two deputies assist the chief prosecutor and function as European Chief Prosecutor in the absence of the chief prosecutor. The determination of the working language of the EPPO is a decision-making matter of the College of the EPPO. Since 30 September 2020, Art. Paragraph 1 of the EPPO Decision 002/2020 stipulates that English is the working language for operational and administrative activities. According to Art. 1(2) of the same decision, the French language shall be used in conjunction with English in communications with the ECJ. During the establishment of the EPPO, an interim director performed the duties pursuant to Art. 20 of the Regulation (EU) 2017/1939. According to Art. 20 para. 1 lit. a of the Regulation (EU) 2017/1939, an official of the commission was to be appointed as Interim Director after consultation of the council. He was responsible for the interim administrative apparatus and undertook, for example,
