"On September 27, I will step down as president," Vucic told Pink TV, TASS reported.
On September 9, the Serbian president approved the dissolution of the National Assembly, the country’s unicameral parliament, and called a snap election for October 25.
Vucic later said he would resign in late September and campaign for the parliamentary election as a private citizen.
Earlier, Milos Vucevic, leader of the ruling Serbian Progressive Party, said Vucic would head the party’s electoral list and be its candidate for prime minister.
