The latest development of the Czech party system is mainly characterized by increasing electoral support of genuinely new political parties, namely Věci Veřejné in 2010 and ANO in 2013. Such initial success has far reaching consequences to the development of internal organizational structure of new political parties.
The article deals with phenomenon of elec- toral success of those genuinely new political parties in the perspective of institutionalization theory which is capable to explain their formation and organizational development. The primary goal of the article is to analyse processes leading to stabilisation or failure of intra-party structures and organization as a whole.
