This paper aims to analyze the development of parliamentary systems in Ukraine.Since independence, Ukraine held parliamentary elections three times (1994, 1998, 2002) .There are many articles which analyzed these elections. Their approaches were characterized by two. First of all, they were using the left-right ideology scale to analyze them. For instance, parliamentary camps would be classified by this scale. The Communist party of Ukraine was located on the left edge, on the other hand Ukraine nationalists parties were located on the opposite side. Secondly, the political party was their central analysis unit in these studies.However, these approaches have two problems. First, ideology issues are not the central matter of current political arena. It is insignificant to use this scale to classify today's the political parties. Second, political parties are less important actors during the elections and the session of the parliament. As for elections, independent candidates and the electoral blocks are dominant. Also, parliamentary procedures are ran by the fractions, which are the compositions of independents, parties and blocks. There is little coincidence between the three. This is especially for independents who are less ideologized and frequently change their belongings. Once those deputies form their own parties or fractions, few of them are alive by the time of the next elections. Third, these less ideologized deputies, called “Centrist, ” become more important within the current political arena. We should consider these forces as a main unit of our research.The Centrists begin their career as a high rank bureaucrat or directors of large state industries. Since each of them individually retained certain political resources, they did not form any organization such as political party. The rise of the Super-Presidentilaism and the large scale economic reform as well as the introduction of proportional representation, all had an impact on these Centrists. New counter-elites emerged from the privatization and diversification of economic interests, confront old elites. This drove old and new elites to organize each political structure to compete against each other. Also, they had a interest to support the president not to revive old communist regime.Last year's elections proved the above mentioned tendency. The ideologized parties lost their momentum. On the other hand, the Centrists' parties gained more seats than the previous elections. Furthermore, we observed that the Centrists' split into pro and anti presidential camps within the parliament. This will be the strong evidence of how Ukrainian parliament works well.
