The paper deals with the question of party system change in the Czech Republic since the 2010 parliamentary elections. Although at least since the mid-1990s the Czech party system was considered to be one of the most stable party systems in the CEE countries, since the 2010 elections the Czech party system has been undergoing major transformation of its format and structure, mainly because of a drastic change of voter behaviour in the 2010 and 2013 parliamentary elections.
