Georgian police fire tear gas as protesters try to enter presidential palace

With 73 percent of precincts reporting, the central election commission said Georgian Dream had won municipal council races in every municipality with more than 80 percent of the vote.

Ahead of the demonstration, authorities pledged a tough response to those it cast as seeking "revolution".

Waving Georgian and EU flags, tens of thousands flooded Tbilisi's Freedom Square for what organisers dubbed a "national assembly", an AFP reporter saw. 

The normally low-key local elections have acquired high stakes after months of raids on independent media, restrictions on civil society and the jailing of dozens of opponents and activists.

Opera star–turned–activist Paata Burchuladze attended the Freedom Square demonstration to read out -- to loud applause -- a declaration claiming "power returns to the people," branding the government "illegitimate" and announcing a transition.

Demonstrators then marched toward the presidential palace and tried to enter the compound, prompting law enforcement to fire tear gas and water cannon. Protesters erected barricades and set them on fire.

"They had announced the overthrow of the constitutional order and its violent replacement and took concrete steps toward that. Every person involved in this violent act will be prosecuted," Kobakhidze told reporters.

He accused EU officials of backing an "attempt to overthrow the constitutional order" and urged the bloc's ambassador to condemn the unrest, saying the envoy shares responsibility.

The interior ministry said it had launched an investigation into "calls to violently alter Georgia's constitutional order or overthrow state authority."

Jailed reformist ex-president Mikheil Saakashvili had urged supporters to protest on election day for what he called the "last chance" to save Georgian democracy.

Without action, "many more people will be arrested and the rest driven out," he warned. "Total hopelessness will take hold and the West will finally give up on us."

"Anyone who cares about Georgia's fate should be out here today," 77-year-old protester Natela Gvakharia told AFP. "We are here to protect our democracy, which Georgian Dream is destroying."

Rights groups say some 60 people -- among them key opposition figures, journalists and activists -- have been jailed over the past year.

Amnesty International said the elections were "taking place amid severe political reprisals against opposition figures and civil society".

Georgian Dream has been in power since 2012.

It is controlled by billionaire former prime minister Bidzina Ivanishvili, who voted in Tbilisi early on Saturday morning, surrounded by cameras.

- 'Deep state' -

Georgian Dream initially presented itself as a liberal alternative to Saakashvili's reformist camp.

But since Russia's full-scale invasion of Ukraine in 2022, critics say it has tilted towards Moscow, pursuing far-right policies and adopting Kremlin-style measures targeting independent media and NGOs.

Georgian Dream says it is safeguarding "stability" in the country of four million while a Western "deep state" seeks to drag Georgia into the war in Ukraine with the help of opposition parties.

Analysts say its blunt pitch -- claiming that the opposition wants war, but it wants peace -- resonates in rural areas and is amplified by disinformation.

A recent survey by the Institute of Social Studies and Analysis put the party's approval rating at about 36 percent, against 54 percent for opposition groups.

The European Union has sanctioned several Georgian Dream party officials over previous crackdowns on protestors.

It warned it could suspend Georgians' right to visa-free travel to the EU unless the government improves the rule of law and protects fundamental rights.
