This chapter focuses on the actual coordination and decision-making between the president and the prime minister. The analysis covers agenda-setting initiatives, public opinion and party system dynamics, and the way formal prerogatives are interpreted into praxis, as well as how the key actors approach coordination where there is no explicit constitutional or judicial guidance. The findings confirm that lack of written rules or otherwise strong norms guiding intra-executive coordination opens the door for presidential activism (Lithuania and particularly Romania), whereas under stronger coordination mechanisms, presidents are in turn more constrained and constructively involved in decision-making (Finland).
