The 2013 Czech political corruption scandal started with a raid against organized crime which was conducted in the Czech Republic in June 2013 by the Police Unit for Combating Organized Crime (Czech: Útvar pro odhalování organizovaného zločinu, ÚOOZ) and the Chief Public Prosecutor's Office (Vrchní státní zastupitelství) in Olomouc. It involved several highly positioned state officers and politicians, as well as controversial entrepreneurs and lobbyists. The scandal affected the top levels of Czech politics, including Prime Minister Petr Nečas and his coalition government. On 17 June 2013, it resulted in the resignation of the Prime Minister and the cabinet. Nečas also quit as leader of the Civic Democratic Party (ODS).
The investigation of the case started in early 2012, according to Robert Šlachta, the head of the Unit for Combating Organized Crime. Ivo Ištvan, the Chief Public Prosecutor in Olomouc, confirmed that a total of 400 policemen were deployed in the raid.
On 13 June 2013, some of the closest advisors and collaborators of the Czech Prime Minister, including Jana Nagyová, Managing Director of the Section of the Prime Minister of the Czech Republic's Cabinet, and Lubomír Poul, Director of the Office of the Government, were arrested in association with unspecified misconduct. Ondrej Páleník, former head of the Military Intelligence Service; Milan Kovanda, current head of the Military Intelligence Service;Ivan Fuksa, former Minister, and Petr Tluchoř, former Deputy, were among the arrested as well. The seat of the Government of the Czech Republic and offices of several influential Prague lobbyists were raided by police. The whereabouts of Petr Nečas after the arrests were not known, however, later he announced that his confidence in Nagyová "had not decreased". He also denied speculation about his resignation.
