Opposition leaders denounced the results of the parliamentary elections, accusing the Central Election Commission of “filling a dirty order” from the leader of the ruling party, Bidzina Ivanishvili.
Nika Gvaramia, one of the opposition leaders called the results "a constitutional coup".
According to the results announced by the electoral commission, the main opposition groups, including the Coalition for Change, Unity bloc, Strong Georgia, and For Georgia obtained 37,58% of the votes in total.
Preliminary figures show that overseas voters favored the opposition, with the Coalition for Change receiving 29%, Unity bloc 20.8%, Strong Georgia 14%, and For Georgia 8.4%. Georgian Dream secured just 17.7% of the diaspora vote.
Despite its overall win, Georgian Dream lost in the capital and other major cities.
But Georgian Dream's reclusive billionaire founder Bidzina Ivanishvili, who had campaigned heavily on keeping Georgia out of the war in Ukraine, claimed success on Saturday night.
Ivanishvili's Georgian Dream says it wants Georgia to join the European Union, though Brussels says the country's membership application is frozen over what it says is Georgian Dream's authoritarian tendencies.
The results, if proven true, is a blow to pro-Western Georgians, who had cast the election as a choice between a ruling party that has deepened ties with Russia, and an opposition that had hoped to fast-track integration with the European Union.
Local civil society groups monitoring the election have echoed the opposition's concerns. A coalition of non-governmental organizations claimed there was a "complex process of electoral fraud" and called for the annulment of the official results.
One local monitoring organisation called for the results to be annulled, based on reports of voter intimidation and vote buying, but it did not immediately provide evidence of large-scale falsification.
Several local and international monitoring organizations, including the Organization for Security and Co-operation in Europe (OSCE), are expected to comment on the results on Sunday.
