Socialist Party of Serbia

Zarkula was elected to the Vršac municipal assembly in the 1996 Serbian local elections. The Zajedno (English: Together) coalition won a narrow majority victory in the municipality, and he initially led the SPS's group in opposition.^[3] In September 1997, the Serbian Renewal Movement (Srpski pokret obnove, SPO) assembly group withdrew from Zajedno, and the Socialists were able to form a new administration with Zarkula as assembly president, a position that was at the time equivalent to mayor.^[4]

SPS leader Slobodan Milošević was defeated by Vojislav Koštunica of the Democratic Opposition of Serbia (Demokratska opozicija Srbije, DOS) in the 2000 Yugoslavian presidential election, a watershed moment in the political culture of Yugoslavia and Serbia. The DOS also won a landslide victory in Vršac in concurrent the 2000 local elections, and Zarkula's first term as mayor came to an end.^[5] After the election, he became director of the Millennium Center in the community.^[6]

Movement of the Vršac Region

Zarkula joined the local Movement for the Vršac Region–European Region political organization after 2000. This group was described as "close to the SPS," and Zarkula continued to hold a membership in the Socialist Party for several years afterward.^[7]

Serbia introduced the direct election of mayors for the 2004 Serbian local elections and also separated the positions of mayor and assembly president. Zarkula ran for another term as mayor of Vršac and won a narrow victory over incumbent Milorad Đurić of the Democratic Party (Demokratska stranka, DS). In 2005, Zarkula signed a major agreement on road reconstruction in the community with the Serbian government and the European Agency for Reconstruction.^[8]

The direct election of mayors was ultimately a short-lived experiment; with the 2008 local elections, Serbia adopted a system in which mayors were chosen by the elected assembly members. Zarkula was re-elected to the Vršac assembly that year on the electoral list of the Movement for the Vršac Region. He was not chosen for another term as mayor. Zarkula was also elected to the Vojvodina assembly in the concurrent 2008 provincial election and served with the assembly group of the Socialist Party, becoming its deputy leader.^[9] The SPS joined a coalition government led by the For a European Vojvodina alliance after the election, and Zarkula was a supporter of the administration. He was also appointed as a state secretary as Serbia's ministry of infrastructure, serving under SPS minister Milutin Mrkonjić.^[10] After Vojvodina's conflict-of-interest laws were reformed in 2011, he was required to resign both of his assembly seats to continue as a state secretary.^[11][12] He continued in office after the ministry was given additional responsibility for energy in April 2011.^[13]

Zarkula was expelled from the SPS in 2012 and stood down as a state secretary in that year. He appeared in the second position on the electoral list of the Movement of the Vršac Region in the 2012 local elections and was re-elected when the list won a plurality victory with fifteen out of forty-five seats.^[14][15] When the new assembly convened, he was chosen as its president.^[16]

In November 2015, he became the leader of the Movement for the Vršac Region.^[17] He appeared in the lead position on its list for the 2016 local elections and was re-elected when the list won seven seats.^[18][19] He was confirmed for another term as assembly president after the election.^[20]

Serbian Progressive Party

The Movement for the Vršac Region voted to dissolve itself in late 2016, and in October of that year Zarkula joined the Progressive Party (which already had a majority in Vršac assembly).^[21] He stood down as assembly president in September 2017 and served the remainder of his term as an SNS delegate.^[22][23] He was not a candidate in the 2020 local elections.
