This party advocated liberal and anti-communist ideas and boycotted all elections during the reign of Slobodan Milošević. In 2003 Nikola Milošević became a member of the Serbian Parliament since the Serbian Liberal Party participated in December 2003 elections as a coalition partner of the Democratic Party of Serbia.
