Throughout the history of political parties of their organizational structure has undergone great changes. In modern developed democratic countries, political party structure consists of a number of different interest groups and pressure. Despite the common association ideological, social and political objectives and interests of these groups within the political parties are trying to fiht and compete for leadership in the policy-making process. The most important internal feature of modern political parties is forming the system of coordination of interests within the party. First of all this is achieved by creating a system of communication interaction interest groups, the party elite and counter-elite. The relationship between these elements of the party depends largely on the existing system of party discipline, party ethics and the existing hierarchical system of interaction between the party leadership and «ordinary» members of the party, between central hierarchical structures of the party and the local, between party members included in the various parliamentary and governmental and nonparliamentary groups within the party and so on. Ensure optimal form of inner communication is the formation of interest groups Institute of party democracy. In most developed countries, certain elements of party democracy established by law. Similar rules exist in the legislation of Germany, Italy, Spain, Greece, Albania, Andorra, Armenia, France, Romania, Czech Republic and Portugal. Internal party democracy is not threatened by party discipline and intervention of public authorities in the hierarchical and organizational features of inner communication. A clear manifestation of internal party democratization process of interaction is the introduction of «primaries». This allows you to adjust the relationship between interest groups within political parties without increased competition for leadership and possible negative consequences.
