Belgrade, 26 September (RFE/RL) - Opposition candidate Vojislav Kostunica has rejected the possibility of a runoff vote against Yugoslav President Slobodan Milosevic. Kostunica said a second round in the presidential election would be an "insult" to voters. Kostunica told the independent Beta news agency said Milosevic's Socialists were trying to "bargain their way" into a second round. He said the offer of a second round "can and must be rejected." Earlier today the Yugoslav Federal Electoral Commission announced Kostunica finished ahead in Sunday's vote but failed to win an absolute majority, requiring a runoff. In the first official results since the vote, the commission said Kostunica won 48 percent of the votes and Milosevic got 40 percent. The opposition earlier had said Kostunica had won an outright victory with 54 percent against 35 percent for Milosevic. Kostunica said the opposition would avoid careless moves which could raise tensions and lead to "unforseeable consequences."
