O zagadnieniu współpracy organów władzy wykonawczej w systemach półprezydenckich

The following review presents a recently published monograph written by Tapio Raunio and Thomas Sedelius which tackles the issue of formal and informal aspects of the semi-presidential model of the political system. The book covers three cases: Finland, Lithuania, and Romania. The authors have thoroughly discussed both the institutions for coordinating cooperation between presidents and prime ministers and the informal paths of presidential influence. Such influences are factors that destabilise the regular coordination of exercising the executive power. It is found that the key factors that destabilise cooperation of presidents and prime ministers are: the political culture of a particular society and the type of political leadership presented by each president.
