[3] Obradović later co-founded Social Democracy, and Slavković joined the new party, receiving the fourth position on its list in Niš for the 1997 parliamentary election.
[5] Social Democracy later participated in the Alliance for Change and the Democratic Opposition of Serbia (Demokratska opozicija Srbije, DOS), both of which were broad and ideologically diverse coalitions of parties opposed to Slobodan Milošević's continued rule.
Slavković spoke at a major opposition rally in Pirot in August 1999, calling on Milošević to save Serbia by leaving office.
[6] Milošević was defeated by DOS candidate Vojislav Koštunica in the 2000 Yugoslavian presidential election, an event that brought about watershed changes in Serbian politics.

Slavković aligned himself with this party and appeared in the 208th position on the "Defense and Justice" electoral list led by Obradović and Borivoje Borović in the 2003 Serbian parliamentary election.
He served as the director of "Blok signal doo" Niš and became active in the local media, hosting on RTV Belle Amie and writing for Narodne novine.
[25] Slavković subsequently made disparaging comments against Južne vesti, the news outlet that reported the Facebook exchange, at one point describing its leaders as "foreign mercenaries.
[30] This claim has since been repeated in several media reports; Niš mayor Zoran Perišić, however, clarified that Slavković had not actually been expelled from the party, although a proposal had been brought forward to this end.
