More than one-hundred-thousand people have been attending a rally in Belgrade against President Slobodan Milosevic of Yugoslavia.
Organisers demanded Mr Milosevic's resignation within two weeks.
In a dramatic development, the controversial opposition leader, Vuk Draskovic, addressed the rally despite having earlier withdrawn as a speaker.
The BBC Belgrade correspondent says the mood was electric, with the protestors chanting, 'We want Vuk'.
But in a sign of continuing opposition splits, Mr Draskovic's speech was sometimes drowned by boos.
The Belgrade rally was the culmination of a series around the country.
President Milosevic's Socialist Party earlier revealed plans for early general elections, in an apparent move to diminish support for the opposition.
