ON NATURE OF PRESIDENTIAL SYSTEM OF DEMOCRACY IN NIGERIA
The presidential system of democracy in existence in Nigeria is defined by the separation of the executive branch headed by the President, who unilaterally chooses his team outside the legislature.
The head of government is elected to work alongside but not as a part of the legislature, as in the parliamentary system of democracy.
