Unitary state

  Unitary states
  Federal states

A unitary state is a state governed as a single power in which the central government is ultimately supreme. The central government may create (or abolish) administrative divisions (sub-national units).[1] Such units exercise only the powers that the central government chooses to delegate. Although political power may be delegated through devolution to local governments by statute, the central government may abrogate the acts of devolved governments or curtail (or expand) their powers. A large majority of the world's states (165 of the 193 UN member states) have a unitary system of government.[2]

Unitary states stand in contrast with federations, also known as federal states. In federations, the sub-national governments share powers with the central government as equal actors through a written constitution, to which the consent of both is required to make amendments. This means that the sub-national units have a right of existence and powers that cannot be unilaterally changed by the central government.[3]

The United Kingdom of Great Britain and Northern Ireland is an example of a unitary state. Scotland, Wales and Northern Ireland have a degree of autonomous devolved power, but such power is delegated by the Parliament of the United Kingdom, which may enact laws unilaterally altering or abolishing devolution (England does not have any devolved power). Similarly in the Kingdom of Spain, where the devolved powers are delegated through the central government.[4] Many unitary states have no areas possessing a degree of autonomy.[5] In such countries, sub-national regions cannot decide their own laws. Examples are Romania, the Republic of Ireland and the Kingdom of Norway.[6]
