The ruling Georgian Dream party’s disputed victory in the country’s Oct. 26 parliamentary election, which was widely seen as a referendum on Georgia’s aspirations to join the European Union, has sparked major demonstrations and led to an opposition boycott of the parliament.

The opposition has said that the vote was rigged with the help of Russia, Georgia’s former imperial master, with Moscow hoping to keep Tbilisi in its orbit.

The government’s announcement that it was suspending negotiations to join the EU came hours after the European Parliament adopted a resolution that condemned last month’s vote as neither free nor fair. It said the election represented another manifestation of Georgia’s continued democratic backsliding “for which the ruling Georgian Dream party is fully responsible.”

European election observers said October’s vote took place in a divisive atmosphere marked by instances of bribery, double voting and physical violence.
