The United Democratic Forces of Belarus (Belarusian: Аб'яднаныя дэмакратычныя сілы Беларусі, romanized: Ab'jadnanyja demakratyčnyja siły Biełarusi; Russian: Объединённые демократические силы, romanized: Ob"edinyonnye demokraticheskie sily) is a coalition of political parties that oppose the presidency of Alexander Lukashenko, who has been in power since 1994. It was the main opposition group during the 2006 presidential election and chose Alexander Milinkevich as their candidate.
Official Belarusian statistics reported Milinevich gained 6% of the vote, however Belarusian opposition and critics from Western countries have not accepted the official results as legitimate and believe this is an example of election fraudulence. Belarusian authorities have denied all accusations of election fraud.
