BELGRADE - Serbia's main opposition party accused the dominant pro-Western Democratic Party on Thursday of stealing 500,000 votes in weekend elections and threatened to call supporters into the streets after an upcoming presidential run-off.

The opposition rightist Serbian Progressive Party (SNS) narrowly won a parliamentary election on Sunday but faces being locked out of government by a renewed coalition of the Democratic Party and its allies.

On the steps of parliament, SNS leader Tomislav Nikolic tipped what he described as thousands of unused ballot papers on the ground, saying they were found dumped in a garbage container, and accused the Democrats of adding the names of dead people to the voter list.

"We'll prove they stole 15 percent of the votes," Nikolic told reporters. "They took the names of 500,000 dead people and listed them as voters. The dead cannot complain."
