The European Union employs a variety of public accountability measures to review and reform budgets across government.^[1] As the EU's budget is at risk of maladministration, every year the Court of Auditors reports on the management of the budget. European Union auditors have stated that as they implement more transparency and double-entry book-keeping systems, it is likely to improve budget management.^[2]

In order to strengthen the means of fraud prevention, the commission established the European Anti-Fraud Office, also known as OLAF, on 28 April 1999, under the European Commission Decision 1999/352.^[3][4] The Office was given responsibility for conducting administrative anti-fraud investigations by having conferred on it a special independent status.

The Court of Auditors checks that all the Union's revenue has been received and all its expenditure incurred in a lawful and regular manner and that the EU budget has been managed soundly. The Court was established on 22 July 1975 by the Budgetary Treaty of 1975. The Court started operating as an external Community audit body in October 1977.

The meetings of the Council of Ministers (the relevant Minister from each member state) are mostly public. A webcast on the sessions can also be seen on the website of the council.^[5]

Also, the standard of plenary sittings of the European Parliament is to stream the debates over the Internet.^[6] In addition, the public can observe sittings directly from a separate gallery. Also, nearly all sittings of Parliamentary Committees are observable by the public,^[7] except for certain matters such as requests for removal of the parliamentary immunity of a Member of the European Parliament.

In addition, the activities of the European Commission are subject to transparency. The monitoring of the commission has to be performed by a body that is independent of the commission, such as "European Anti-Fraud Office" (OLAF) that reports to the European Parliament.^[8]

European Parliament adopted binding rules on lobby transparency in 2019, where MEPs involved in drafting and negotiating legislation must publish their meetings with lobbyists.^[9] The amendment says that "rapporteurs, shadow rapporteurs or committee chairs shall, for each report, publish online all scheduled meetings with interest representatives falling under the scope of the Transparency Register"-database of the EU.^[10]

European Parliament officials have been accused of corruption and money laundering due to inference by the governments of Qatar, Morocco, Mauritania,^[11] and Russia, also called Qatargate and Russiagate.^[12][13][14]

Parliamentary Assembly of the Council of Europe adopted a motion which states that "it regrets the fact that Members of the European Parliament have accepted and failed to declare trips to Azerbaijan, visits to the Nagorno-Karabakh region and luxury hotel stays that were organised and paid for by Azerbaijani officials."^[15]
