PRESIDENTIAL SYSTEM OF GOVERNMENT
Presidential system of government is defined as one in which the head of state of a country is also the head of government. It is a system in which all executive powers are vested in one person with the title of the executive president.
The constitution of a presidential system of government is supreme and has succeeded in depositing the offices of the head of state and government in the executive president. For example, in Nigeria’s Second Republic of 1979/ 83, President Shehu Shagari was both the Head of State and Government of Nigeria, exercising executive powers within the system.
He was also the Commander-in-Chief of the armed forces and the police force. The 1999 constitution of the Federal Republic of Nigeria that ushered in the Third Republic also gave the same powers to President Olusegun Obasanjo.
The whole country is the president’s constituency and he is popularly elected by the electorate. To assist is a vice president to whom he can delegate some of his duties. The principle of separation of powers among the three organs of government; executive, legislature and judiciary, is strictly adhered to in this system. The United States of America is a good example of a country wholly committed to presidential system.

FACTORS THAT LED TO THE INCREASING POPULARITY OF THE PRESIDENTIAL SYSTEM OF GOVERNMENT IN WEST AFRICA
- Colonial Legacy: The parliamentary system, a colonial legacy from Britain on her former West African colonies could not guarantee desired political stability after independence.
- Traditional African Political System: The presidential system resembles the traditional African political system, as separating the offices of Heads of State and government is not only meaningless in Africa but also difficult to achieve.
- Quick Decision-making: The process of decision-making is quick and orderly because of the absence of opposition.
- Collective Responsibility: It eliminates the parliamentary collective responsibility, a requirement of all cabinets resigning because of one man’s mistake.
- Nation-building: Looking at the mode of his election and his powers, the president is capable of instituting a strong executive that can promote a faster rate in the process of nation-building.
- Division of Ceremonial and executive functions: The friction and bickering that characterises the parliamentary system as a result of the division of ceremonial and executive functions is removed.
- Responsibility for Certain function: It is easier to identify who has responsibility for certain function and who’s to blame for lapses or inaction.
