The changes in political life in Poland in the period 2005–2011, which restructured the existing balance of power (dominance of post-Solidarity parties at the expense of the post-communist party) force us to consider whether the party system evolution involves changes in the sphere of ideological divisions. But there also arises another question about the crisis of the left, which could mean the end of the previous model, intergroup rivalry. But there is no doubt that it occurred after 2005 events. Initiated processes took a completely different direction than those in the 90^s. The purpose of the article is to explain the ongoing political disputes, and also attempt to answer the question: what factors shape the profile of program-ideological political formations in Poland.
