More than 7,000 protestors gathered in the of the Moldovan capital Chisinau on Monday to protest the Communist government and its alleged corruption, the Infotag news agency reported.
The peaceful demonstration organized by opposition groups moved through the city centre without incident. The march was the largest yet seen in the run-up to parliamentary elections scheduled for April 5, reported dpa.
Marchers shouted slogans, including "Get corruption out of the country!", "Down with the Communist Party!" and "Just leave now!"
Anatol Peterencu, one of the organizers, accused Moldova's Communist government of "bringing the nation to destitution."
Communists control most television stations, making protest marches a favoured opposition tactic for pitching anti-government political programmes to the general public.
Independent observers, including Transparency International have rated Moldova among Europe's most corrupt nations, where state officials are likely to be on the take, and on par with Belize and the Solomon Islands.
Moldova has rated poorly on international corruption ratings continuously since independence in 1991. Its Communists came to power in 2001.
