[1][2][3] Petrović appeared in the third position on a coalition electoral list of the Socialist Party of Serbia (SPS), the Yugoslav Left, and New Democracy (ND) in Kragujevac for the 1997 Serbian parliamentary election.
New Democracy later ended its alliance with the Socialist Party of Serbia and the Yugoslav Left, and in July 1999 the ND delegates in the Serbian assembly had their mandates revoked under controversial circumstances.
[10] During the 1990s, Serbia's political culture was dominated by the authoritarian rule of SPS leader Slobodan Milošević and his allies.
Milošević fell from power after being defeated by Democratic Opposition of Serbia (DOS) candidate Vojislav Koštunica in the 2000 Yugoslavian presidential election.
She continued to serve as a JUL delegate in the Kragujevac city assembly until 2004, making her one of the last party members to hold elected office in Serbia.
