A member of the Socialist Party of Serbia (SPS), he also served as acting minister of education after the resignation of Branko Ružić.

In a 2011 interview, he said that he joined the party "at the time when it was hard being a Socialist"; he added that he became politically active in order to participate in "the struggle for an economically prosperous and culturally developed society where people will have equal chances in life.

The Socialist Party lists in 2000 and 2003 were mostly alphabetical; Milićević could have been awarded a mandate despite his relatively low position, although in the event he was not.

[8][9] The list won twenty seats, and he was on this occasion chosen as part of the party's assembly delegation.

For us the only acceptable way is the government policy that Serbia is conducting, and that is the defence of its national integrity and territorial sovereignty, and the EU.

"[14] Serbia's electoral system was reformed in 2011, such that parliamentary mandates were awarded in numerical order to candidates on successful lists.

[16] In February 2013, he dismissed suggestions about tensions between the Socialists and Progressives, saying that the parties were united on core issues.
