In a parliamentary system, the role of a president often differs significantly from that in a presidential system. In parliamentary systems, the president may serve a primarily ceremonial role, with the prime minister holding the majority of executive power. Conversely, in presidential systems, the president is typically the head of state and government, possessing significant authority and independence. This distinction impacts governance dynamics, with parliamentary systems often emphasizing collaboration and consensus, while presidential systems may feature a stronger separation of powers and executive authority.
