Serbian Radical Party leader Tomislav Nikolic, widely branded an ultra-nationalist, is challenging incumbent President Boris Tadic, with both candidates level in opinion polls. Nikolic gained a five-point advantage in the first voting round on January 20.
In a live TV debate held late on Wednesday Tadic said Serbia was at a crossroads as the country had to choose whether to continue its integration with the European Union or face isolation.
Meanwhile, Nikolic said that Serbia had two roads: one, which was open towards the Russian Federation, and the other, which had many obstacles, towards the European Union.
Both Tadic and Nikolic are strongly opposed to the independence of Serbia's breakaway province of Kosovo, but Nikolic has promised a tougher stance on relations with the European Union if it recognizes the breakaway province's statehood.
Serbia's predominantly Albanian province of Kosovo has been a UN protectorate since the NATO bombing of the former Yugoslavia ended a conflict between Albanian and Serb forces in 1999.
