The paper addresses a concept of differentiated integration in Slovenian politics. The analysis showed that the key words associated with the salience of DI are seldom used in parliamentary debates, coalition programmes or prime minister speeches. The issue of DI is more a topic for academic discussion than for daily politics. We identify that the common thread throughout Slovenian foreign policy from independence onwards has been that a strong and united EU, which is of key importance for Slovenia. Primarily because of a fear that a multi-tier EU would mean fewer opportunities for future Slovenian governments and in general fewer opportunities for smaller and/or less developed countries.
