The last election in the Slovak and Czech Republic was special. It not only took place before the official electoral period (pre-elections), but new political parties were “again” successful. The article focuses not only on both elections in the last two years in a comparative perspective, but it analyses the opportunity structure of success as well, including types of new political parties (according to Lucardie). The article seeks to answer the question: why are new political parties electorally successful, able to break into parliament and even become part of a coalition government? We assume that the emergence and success of new political parties in both countries relied on the ability to promote “old” ideas in a new fashion, colloquially referred to as “new suits” or “old” ideological flows in new breeze.
