Heads of state in the context of "Advice (constitutional)"

The European Council (informally EUCO) is a collegiate body (directorial system) and a symbolic collective head of state, that defines the overall political direction and general priorities of the European Union (EU). It is composed of the heads of state or of government of the EU member states, the president of the European Council, and the president of the European Commission. The High Representative of the Union for Foreign Affairs and Security Policy also takes part in its meetings.

Established as an informal summit in 1975, the European Council was formalised as an institution in 2009 upon the commencement of the Treaty of Lisbon. Its current president is António Costa, former prime minister of Portugal.

An indirect election or hierarchical voting, is an election in which voters do not choose directly among candidates or parties for an office, but elect people who in turn choose candidates or parties. This electoral system is one of the oldest forms of elections and is used by many countries for heads of state (such as presidents), heads of government (such as prime ministers), and/or upper houses. It is also used for some supranational legislatures. The body that controls the federal executive branch (such as a cabinet) is in many countries elected indirectly by the head of government with exception of the directorial system. Upper houses, especially in federal republics, are often indirectly elected, either by the corresponding lower house or cabinet.

Positions that are indirectly elected may be chosen by a permanent body (such as a parliament) or by a special body convened solely for that purpose (such as an electoral college). An election can be partially indirect, for example in the case of indirect single transferable voting, where only eliminated candidates select other candidates to transfer their vote share to. Similarly, supranational legislatures can be indirectly elected by constituent countries' legislatures or executive governments.

Founded in 1278 by a treaty between the bishop of Urgell and the count of Foix, this unique diarchical arrangement has persisted through the Middle Ages to the present. Following the transfer of the count of Foix's claims to the Crown of France and, subsequently, to the head of state of the French Republic, the current arrangement has the bishop of Urgell (Josep-Lluís Serrano Pentinat) serving as the episcopal co-prince and the president of France (Emmanuel Macron) as the lay co-prince. Each co-prince appoints a personal representative. The episcopal co-prince is currently represented by Eduard Ibáñez and the lay co-prince by Patrice Faure.

In international law, extraterritoriality or exterritoriality is the state of being exempted from the jurisdiction of local law, usually as the result of diplomatic negotiations.

Historically, this primarily applied to individuals, as jurisdiction was usually claimed on peoples rather than on lands. Extraterritoriality can also be partly applied to physical places. For example, such is the immunity granted to diplomatic missions, military bases of foreign countries, or offices of the United Nations. The three most common cases recognized today internationally relate to the persons and belongings of foreign heads of state and government, the persons and belongings of ambassadors and other diplomats, and ships in international waters.

There are seven Scottish Government offices based in British embassies or British High Commission offices.
