These are systems in which the head of state is a constitutional monarch; the existence of their office and their ability to exercise their authority is established and restrained by constitutional law.
Systems in which a prime minister is the active head of the executive branch of government. In some cases, the prime minister is also leader of the legislature, while in other cases the executive branch is clearly separated from legislature (although the entire cabinet or individual ministers must step down in the case of a vote of no confidence).[1][2][dubious – discuss] The head of state is a constitutional monarch who normally only exercises his or her powers with the consent of the government, the people and/or their representatives (except in emergencies, e.g. a constitutional crisis or a political deadlock).[lower-alpha 1]

United Kingdom[lower-alpha 3]In a parliamentary republic, the head of government is selected or nominated by the legislature and is also accountable to it. The head of state is usually called a president and (in full parliamentary republics) is separate from the head of government, serving a largely apolitical, ceremonial role. In these systems, the head of government is usually called the prime minister, chancellor or premier. In mixed republican systems and directorial republican systems, the head of government also serves as head of state and is usually titled president.
In some full parliamentary systems, the head of state is directly elected by voters. Under other classification systems, however, these systems may instead be classed as semi-presidential systems as presidents are always attached to a political party and may have broad powers (despite their weak presidency).[3] Full parliamentary republican systems with presidents being purely ceremonial and neutral with no broad powers usually do not have a directly elected head of state and instead often use either an electoral college or a vote in the legislature to appoint the president.

A combined head of state and head of government in the form of an executive president is either elected by the legislature or by the voters from among candidates nominated by the legislature (in the case of Kiribati),[17] and they must maintain the confidence of the legislature to remain in office. In effect, "presidents" in this system function the same as prime ministers do in other parliamentary systems.
In presidential systems a president is the head of government, and is elected and remains in office independently of the legislature. There is generally no prime minister, although if one exists, in most cases they serve purely at the discretion of the president.

The following countries have presidential systems where a post of prime minister (official title may vary) exists alongside that of the president. The president is still both the head of state and government and the prime minister's roles are mostly to assist the president.

In a semi-presidential republic a president exists alongside a prime minister and a cabinet, with the latter two being responsible to the legislature. It differs from a parliamentary system in that it has an executive president independent from legislature; and from the presidential system in that the cabinet, although named by the president, is responsible to the legislature, which may force the cabinet to resign through a motion of no confidence.[23][24][25][26]
In a premier-presidential system the prime minister and cabinet are exclusively accountable to the legislature.[27]

In a president-parliamentary system the prime minister and cabinet are dually accountable to the president and the legislature.[27]
Non-UN members or observers are in italics.
A combined head of state and head of government (usually titled president) is elected by the legislature but is not held accountable to it (as is their cabinet), thus acting more independently from the legislature.[27] They may or may not also hold a seat in the legislature.
In a directorial republic, a council jointly exercises the powers and ceremonial roles of both the head of state and head of government collectively. The council is elected by the parliament, but is not subject to parliamentary confidence during its fixed term. The president is a member of the directorial council in a primus inter pares (first among equals) capacity and has no powers over other members of the directory.
Iran combines the forms of a presidential republic, with a president elected by universal suffrage, and a theocracy, with a Supreme Leader who is ultimately responsible for state policy, chosen for life by the elected Assembly of Experts. Candidates for both the Assembly of Experts and the presidency are vetted by the appointed Guardian Council.The prime minister is the nation's active executive, but the monarch still has considerable political powers that can be used at their own discretion.
Specifically, monarchies in which the monarch's exercise of power is unconstrained by any substantive constitutional law. The monarch acts as both head of state and head of government.
States in which political power is by law concentrated within one political party whose operations are largely fused with the government hierarchy (in contrast to states where a multi-party system formally exists, but this fusion is achieved anyway through election fraud or underdeveloped multi-party traditions).

A state governed as a single power in which the central government is ultimately supreme and any administrative divisions (sub-national units) exercise only the powers that the central government chooses to delegate. The majority of states in the world have a unitary system of government. Of the 193 UN member states, 126 are governed as centralized unitary states, and an additional 40 are regionalized unitary states.
States in which most power is exercised by the central government. What local authorities do exist have few powers.
States in which the central government has delegated some of its powers to regional authorities, but where constitutional authority ultimately remains entirely at a national level.

It has elements of intergovernmentalism, with the European Council acting as its collective "president", and also elements of supranationalism, with the European Commission acting as its executive and bureaucracy.[61]
