The SNS, which organised the protest rally in cooperation with the smaller opposition parties the New Serbia, the Socialist Movement, and the Strength of Serbia Movement, called for organising an early parliamentary election in two months' time at the latest, warning that otherwise it would again organise a protest to last until the elections were called.

According to local media, there were no incidents during the protest that was held amidst tight security measures.

The police estimated that some 55,000 people attended the protest.

The protesters were addressed by SNS leader Tomislav Nikolic and officials of the other parties that organised the rally, including New Serbia leader and former Infrastructure Minister Velimir Ilic, who said that Serbia did not want its incumbent government and that it wanted Nikolic as its new leader.

"We don't want Tunis, Cairo and Egypt, but a democratic Serbia. You don't know how to rule, no one in Serbia is satisfied except for you," Ilic said in a message to the government.

The SNS was established in October 2008 by former members of the Serbian Radical Party (SRS) of Vojislav Seselj who backed former SRS deputy president Nikolic after his conflict with Seselj.

According to occasional opinion polls in the media, the SNS is the strongest opposition party in Serbia and the main rival to the Democratic Party, which is the main party of the current coalition government.
