The 2016 Elections to the National Council in Slovakia are considered a political earthquake. Social Democrats lost 34 out of 83 seats, the Euro sceptic party SaS almost doubled its representation, the nationalistic Slovak National Party returned to the Parliament with 15 seats and three "newcomers" entered the Parliament: the (neo) fascist Kotleba -ĽSNS, conservative We are Family (SME RODINA -Boris Kollár) and centrist #Network (#Sieť). Changes in composition raised questions about party system institutionalization and opened a debate about challenging trends within the Slovak party system including fragmentation, aggregation, high volatility, anti -systemness or alternation. Moreover, it again opened the issue of party newness and consolidation. This article deals with current trends in the context of the 2016 elections and tries to examine the current state of the Slovak Party system.
