Before 2000

Miličković appeared in the twenty-second position on the Radical Party's electoral list for Belgrade in the 1993 Serbian parliamentary election.^[2] The party won seven seats in the capital, and he was not included in its assembly delegation.^[3] (From 1992 to 2000, one-third of Serbia's parliamentary mandates were assigned to candidates from successful lists in numerical order, while the remaining two-thirds were distributed amongst other candidates at the discretion of the sponsoring parties and coalitions. Miličković could have been awarded a mandate despite his low position on the list.)^[4]

He was elected to the City Assembly of Belgrade in the 1996 Serbian local elections.^[5]

From 2000 to 2008

The 2000 Yugoslavian general election was a watershed moment in Serbian and Yugoslavian politics, resulting in the defeat of Yugoslavian president Slobodan Milošević and the Socialist Party of Serbia, which had dominated politics in the country for the last decade. Miličković was a candidate for the Chamber of Citizens in the Yugoslavian parliament in this election, appearing in the first position on the Radical Party's list in Čukarica.^[6] He was not successful; the list did not win any seats in the division.^[7] He was also defeated in his bid for re-election to the Belgrade city assembly and for election to the Rakovica municipal assembly in the concurrent 2000 Serbian local elections.^[8]

Following Milošević's defeat, a new election was held for the Serbian national assembly in December 2000. For this election, the entire country was counted as a single electoral division and all mandates were awarded to candidates on successful lists at the discretion of the sponsoring parties and coalitions, irrespective of numerical order.^[9] Miličković appeared in the fifty-fifth position on the Radical list, which won twenty-three mandates.^[10] He was again not included in his party's delegation.

He once again appeared in the fifty-fifth position on the Radical Party's list in 2003 Serbian parliamentary election. On this occasion, the party won eighty-two mandates to become the largest group in the assembly (although it fell well short of a majority and ultimately served in opposition). Milićković was selected for a mandate when the assembly met in January 2004.^[11] His term in the republican parliament was brief: on 12 February, he was appointed as a member of the Radical Party's delegation to the federal assembly of Serbia and Montenegro.^[12] He served in the latter role until 2006, when the assembly ceased to exist after Montenegro declared independence.^[13]

Miličković appeared in the forty-first position on the Radical list for the 2007 Serbian parliamentary election and was given a mandate for a second term when the list won eighty-one seats.^[14][15] An unstable coalition government was formed by the Democratic Party (Demokratska stranka, DS) and the rival Democratic Party of Serbia (Demokratska stranka Srbije, DSS) after the election, and the Radicals continued to serve in opposition.

The DS–DSS coalition collapsed in early 2008, and another election was called for May of that year. Miličković once again appeared on the Radical list; the party won seventy-eight seats, and on this occasion he was not selected for its delegation.^[16][17] He also appeared in the second position on the Radical Party's list for the Rakovica municipal assembly in the concurrent 2008 Serbian local elections and took a mandate when the list won twenty-five out of seventy seats, finishing a close second against the For a European Serbia coalition led by the Democratic Party.^[18][19][20] The Radicals served in opposition at the municipal level following the election.^[21]
