Nové trendy ve vývoji švédského stranického systému.

The article seeks to describe and interpret recent trends within the Swedish party system. The point of departure for analysis is twofold: (1) to describe past development of patterns of cooperation and conflict among Swedish political parties, (2) an examination of P. Mair's concepts on the structure of party system competition and party system change, which are applied to the Swedish case. Special attention is given to the process of formation of the right-wing as well as the left-wing blocs. The aim of the article is to explain why and under what circumstances these blocs emerged, considering the fact that these blocs were at times almost invisible, at times only slightly salient. Moreover, party cooperation often took place across bloc lines. This analysis of past trends serves as a basis for understanding up-to-date developments within the right-wing bloc and particularly left-wing parties, which - for the first time in the Swedish party politics history - have recently declared their intention to form an election alliance and even a government coalition after the 2010 parliamentary elections. The article also discusses the question of whether these trends might lead to a specific version of the two-party system. [ABSTRACT FROM AUTHOR]
