Presidential and parliamentary system

A modern research shows that, both presidential and parliamentary systems are applied in democracy countries. They have advantages and disadvantages, for instance presidential system establishes the presidency and the legislature as two parallel structures. Furthermore, Presidential system provides more stability than a prime minister who can be dismissed at any time. However, other researchers observed that, Presidential system is tendency towards authoritarianism. On the other hand, parliamentary system is a democratic form of government in which the people vote for those who represent the political parties. Moreover, the prime minister is accountable to the parliament, parliament must check the works of government, and for example how they are spending budget or taxes. However, parliamentary system can lead to conflicts among parties and this affects badly on the work of the Government. In addition, both systems can be applied in different countries according to differences in the culture of these countries.
