One of Georgia's opposition parties, European Georgia, has called weekend parliamentary elections unfair and says it will boycott runoff balloting to protest official results that handed the ruling Georgian Dream party its third consecutive electoral victory.

One of the party's leaders, Davit Bakradze, told reporters in Tbilisi on November 2 that the elections held on October 31 "were neither free nor fair" and his party is refusing to accept final results announced by the South Caucasus nation's election officials.

The move comes after the largest opposition party, United National Movement (ENM), also rejected the results of the vote, which international observers characterized as "far from perfect."

Runoff elections will be held in 15 districts, all but ensuring the ruling party will secure a majority in parliament, on November 21.
