Municipal politics

Matić was a member of the Socialist Party of Serbia until being expelled in 1998. He was elected as a councillor in Koceljeva in the 2000 municipal elections and as mayor of the municipality in 2004, on both occasions as an independent candidate.^[2] When direct mayoral elections were abolished following the 2004 campaign, he founded a citizens' group that won ten out of thirty-one municipal assembly seats in the 2008 elections and eighteen seats in 2012.^[3] On each occasion, he was selected by the assembly for a new term as mayor.

Matić's group aligned itself with the Progressives after the 2012 elections. He stood down as mayor in late 2014 and instead became president (i.e., speaker) of the municipal assembly. Under his leadership, the Progressives won landslide victories with twenty-seven out of thirty-one seats in the 2016 local elections and twenty-eight seats in the 2020 elections. Matić remains president of the municipal assembly as of 2020.^[4][5][6][7]
