Tens of thousands of Georgian opposition supporters demonstrated Sunday in the capital Tbilisi against the victory of incumbent President Mikhail Saakashvili in what the opposition alleges were falsified polls, according to dpa. According to differing sources in the Georgian media, between 50,000 and 100,000 people braved the cold to call for the resignation of Saakashvili and demand a second round of voting for president. Georgia's election commission Sunday officially declared Saakashvili the winner of controversial January 5 presidential elections in the Caucasus republic. Saakashvili won 53.4 per cent of the vote in the January 5 poll while Gachechiladze, his closest rival, got 25.6 per cent, the Interfax news agency quoted the state election commission as saying.
