Georgia’s pro-Western opposition disputed the results of the parliamentary election after officials declared the ruling party led the crucial vote that could decide whether the country remains on the path to joining the European Union or comes under Russian sway.

The Central Election Commission said Georgian Dream won 54.8% of Saturday’s vote with almost 100% of ballots counted.

Following a divisive pre-election campaign, initial figures suggest turnout was the highest since the ruling party was first elected in 2012.

Georgian electoral observers, who stationed thousands across the country to monitor the vote, reported multiple violations and said the results “do not correspond to the will of the Georgian people”.

Georgian Dream has become increasingly authoritarian, adopting laws similar to those used by Russia to crack down on freedom of speech. Brussels suspended Georgia’s EU membership process indefinitely because of a “Russian law” passed in June.

Bidzina Ivanishvili, the billionaire founder of Georgian Dream who made his fortune in Russia, claimed victory almost immediately after polls closed, saying: “It is rare in the world for the same party to achieve such success in such a difficult situation.”

He had vowed ahead of the election to ban opposition parties should his party win.

Tina Bokuchava, chairwoman of the United National Movement (UNM) opposition party, accused the election commission of carrying out Mr Ivanishvili’s “dirty order” and said he “stole the victory from the Georgian people and thereby stole the European future”.

She indicated the opposition will not recognise the results and “will fight like never before to reclaim our European future”.

The UNM party said its headquarters were attacked on Saturday while Georgian media reported two people were injured in attacks outside polling stations.

The pre-election campaign in the South Caucasus nation of 3.7 million people, which borders Russia, was dominated by foreign policy and marked by a bitter fight for votes and allegations of a smear campaign.

Some Georgians complained of intimidation and being pressured to vote for the governing party.

Georgian Dream scored its highest share of the vote – polling almost 90% – in the Javakheti region of southern Georgia, 83 miles west of the capital Tbilisi, where it failed to get more than 44% of the vote in any district.

The Associated Press travelled to the region before the election where many people are ethnic Armenians who speak Armenian, Russian and limited Georgian. Some voters suggested they were instructed how to vote by local officials while several questioned why Georgia needed a relationship with Europe and suggested it would be better off allied with Moscow.

Around 80% of Georgians favour joining the EU, according to polls, and the country’s constitution obliges its leaders to pursue membership in that bloc and Nato.

Many fear Georgian Dream is dragging the country towards authoritarianism and killing off hopes of becoming an EU member.
