Christian Democratic National Peasants' Party (2006—2008) Conservative Party (2008—2011, 2012—2015) Alliance of Liberals and Democrats (2015) Cristian Victor Popescu Piedone (born 15 February 1963) is a Romanian businessman and politician who served as mayor of Bucharest's Sector 4 from 2008 until 4 November 2015, when he resigned following the Colectiv nightclub fire and the subsequent 2015 Romanian protests.

Piedone was born in Bucharest, but he spent his early years in Cairo, due to the fact that his parents were working at the Romanian Embassy in Egypt.

[2] Marian Vanghelie declared that, in the 1980s, Piedone was the head of the House of Orders, which delivered food for the communist elite: the nomenklatura, party officials and Securitate officers.

[6] In 2000, he was elected a member of the General Council of Bucharest on the lists of the Social Democratic Party (PSD), becoming also an inspector at the Sector 6 city hall.

[13] Popescu Piedone founded an NGO named Asociația pentru Protecția Cetățeanului ("Association for the Protection of the Citizen"),[14] which drew criticism after receiving donations from the State Lottery, a state-owned company managed by a fellow Conservative Party member.

[25] The National Anticorruption Directorate began investigating the case and they arrested Popescu Piedone on November 6 on charges of abuse of power for not respecting the fire safety laws when authorizing the nightclub.

[26] In April 2016, Popescu Piedone registered as a candidate for the Sector 4 mayorship in the 2016 local elections, but his candidacy was contested by an association of the victims in the Colectiv nightclub fire.

In May 2022, the Bucharest Court of Appeal sentenced Popescu Piedone to 4 years of jail time for abuse of office in regards to the Colectiv nightclub fire trial.

[31][32] As a mayor, Piedone took strong social welfare measures, making him an important populist figure in local, as well as national politics.
