Head of government

A head of government is a top official in the executive branch of a state. This person is often the highest or second-highest official in a country. They may lead a sovereign state, a federated state, or an autonomous region. Most often, they preside over a cabinet. A cabinet is a group of ministers or secretaries who lead specific executive departments. In the world of diplomacy, this role is distinct from the head of state.

While a head of state represents the nation, the head of government manages the actual business of running it.

The specific powers of this leader depend on a country's chosen government system. In parliamentary systems, the head of government is usually the de facto political leader. This means they are the person actually exercising political power. They are typically answerable to a chamber of the legislature. In these systems, a head of state often exists as a figurehead. A figurehead is a leader who holds a formal position but has limited power. They might only act as chief executive under specific constitutional rules or when receiving advice.

Some countries use different structures to divide power. In presidential republics, the head of state and head of government are usually the same person. In absolute monarchies, one ruler also holds both roles. Semi-presidential systems, like the French Fifth Republic established in 1958, share these roles. In France, the president is the head of state and appoints the prime minister. The prime minister serves as the head of government. If the president's party does not control the National Assembly, a situation called cohabitation occurs. During cohabitation, the prime minister and cabinet control domestic policy. The president's influence is then mostly restricted to foreign affairs.

Other systems distribute leadership in unique ways. In communist states, the general secretary of the Communist Party acts as the supreme leader. This person serves as the de facto head of state and government. In China, the Premier is the de jure head of government. De jure means the person holds the position according to the law. However, the Chinese president is a ceremonial office. Since 1993, the general secretary of the Communist Party has held the real power.

Switzerland uses a directorial system. Here, the Swiss Federal Council shares executive responsibilities. Each council member heads a department and votes on proposals for all departments.

Titles for these leaders vary widely across the globe. Prime Minister is the most common title. In German-speaking countries like Germany and Austria, the title is Chancellor. In Ireland, the head of government is called the Taoiseach. Other titles include Premier, Chief Minister, or First Minister. Some titles are used only in specific places, such as State Counsellor in Myanmar or State President in South Africa. In the past, leaders under a dominant monarch had different names. These included titles like vizier, diwan, or mahamantri. Even without formal supreme power, some leaders have been very influential. For example, Otto von Bismarck was the Chancellor of Germany under Emperor Wilhelm I.

In parliamentary systems, the government must maintain the support of the legislature to function. This is often managed through the ability to pass a budget. Without control over state finances, a government is powerless. The legislature can also use a vote of no confidence to remove a government. In bicameral systems, which have two houses of parliament, the lower house usually provides the most oversight. In some countries, like Australia or Italy, the government is answerable to both houses. This oversight ensures the head of government remains accountable to the people's representatives.

There are several ways a head of government may leave office. They might resign after losing a general election or a leadership vote within their own party. They may also leave if they lose a major parliamentary vote regarding finances or confidence. In some cases, a head of state can dismiss a head of government. This happened in 1975 during the Australian Constitutional Crisis when Sir John Kerr dismissed Prime Minister Gough Whitlam. Finally, if a leader dies, a deputy usually takes over. This ensures the government continues to function until a new leader is officially appointed.
