Jablanović was previously the Minister of Communities and Returns in the Government of Kosovo. Then Prime MinisterIsa Mustafa dismissed him from office in February 2015 after a statement in which, as judged from Pristina, he insulted the mothers of Gjakova by calling the students of the attack on the bus with Serbs going to the cemetery "savages" and "freaks".[2] After that incident, Jablanović moved to the Ministry of Labour, Employment, Veterans and Social Affairs of the Government of Serbia, and resigned after the incident with his brother.[3]
Following Jablanović's resignation from the Serb List, he founded the PKS, a splinter party of the Serb List, on 6 April 2017 and registered on 15 May 2017.[4] In June 2017, attacks and conflicts between the two parties became frequent.[5]
