It has campaigned for a more cautious approach to the EU, while maintaining sound relations with both Russia and China.<br /><br /> Radical Party<br /><br /> Polls suggest Vojislav Šešelj’s ultra-nationalist Radical Party is making a comeback. <br /><br /> Last month, a United Nations tribunal acquitted Serbia’s former deputy prime minister on counts of war crimes and crimes against humanity, meaning he is once more able to run for election.
