Features of a Unitary Government are as follows:
A single central all-powerful government: All the powers are vested with one single central government whose authority is supreme over all the parts and people of the state.
Local governments exist at the will of the central government: The local governments are created and vested with powers, by the central government. They work as administrative units of the central government and operate as the central government directs.
Constitution can be written or unwritten: Since there is no division of powers and all the powers belong to the central government, there is no special need for a written constitution. But it may be written or unwritten in accordance with the wishes of the people.
Flexibility of constitution and administration: The central government alone has the power to amend the constitution and in this sense the constitution is always flexible.
