Georgia's ruling Georgian Dream party has scored a landslide win in disputed parliamentary polls, according to official results released on Monday, prompting the main opposition force to allege fraud.

The Central Election Commission said Georgian Dream won in all but two of 50 single-mandate constituencies where a second round was held on Sunday, after it led in the first round on October 8 with 48.68 percent of the vote in a proportional ballot while the rival UNM party came second with 27.11 percent.
