Countries of the present time have different constitutional policies and other rules and regulations. The government bodies have own ways to make decisions and set rules and regulations for their citizens. From the names, it can be understood that parliament is the head of one government and on the other side; the president is the head of the other government. A detailed analysis of the differences is done here. Members of parliament are considered as ministers in parliamentary government but in presidential government, it is the president who elects the ministers and secretaries (Karlsen & Skogerbø, 2015).
