Cabinet (government) in the context of "Federal Council (Switzerland)"

A minister is a politician who heads a ministry, making and implementing decisions on policies in conjunction with the other ministers. In some jurisdictions the head of government is also a minister and is designated the 'prime minister', 'premier', 'chief minister', 'chancellor' or other title.

In Commonwealth realm jurisdictions which use the Westminster system of government, ministers are usually required to be members of one of the houses of Parliament or legislature, and are usually from the political party that controls a majority in the lower house of the legislature. In other jurisdictions—such as Belgium, Mexico, Netherlands, Philippines, Slovenia, and Nigeria—the holder of a cabinet-level post or other government official is not permitted to be a member of the legislature. Depending on the administrative arrangements in each jurisdiction, ministers are usually heads of a government department and members of the government's ministry, cabinet and perhaps of a committee of cabinet. Some ministers may be more senior than others, and some may hold the title 'assistant minister' or 'deputy minister'. Some jurisdictions, with a large number of ministers, may designate ministers to be either in the inner or outer ministry or cabinet.

In the executive branch, the head of government is the highest or the 2nd-highest official of a sovereign state, a federated state, an autonomous region, a dependent territory, a self-governing colony, or other government who often presides over a cabinet, a group of ministers or secretaries who lead executive departments.

In diplomacy, "head of government" is differentiated from "head of state".

A minority government, minority cabinet, minority administration, or a minority parliament is a government and cabinet formed in a parliamentary system when a political party or coalition of parties does not have a majority of overall seats in the legislature. It is sworn into office, with or without the formal support of other parties, enabling a government to be formed. Under such a government, legislation can only be passed with the support or consent of enough other members of the legislature to provide a majority, encouraging multi-partisanship. In bicameral legislatures, the term relates to the situation in the chamber whose confidence is considered most crucial to the continuance in office of the government (generally, the lower house).

A minority government tends to be less stable than a majority government because, if they can unite, opposing parliamentary members have sufficient numbers to vote against legislation, or even bring down the government with a vote of no confidence. If, however, a minority government can negotiate a confidence and supply agreement with parties sufficient to maintain a majority, it can be as stable as a majority government.

A semi-presidential republic, or dual executive republic, is a republic in which a president exists alongside a prime minister and a cabinet, with the latter of the two being responsible to the legislature of the state. It differs from a parliamentary republic in that it has an executive president independent of the 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.

While the Weimar Republic (1919–1933) and Finland (from 1919 to 2000) exemplified early semi-presidential systems, the term "semi-presidential" was first introduced in 1959, in an article by the journalist Hubert Beuve-Méry, and popularized by a 1978 work written by the political scientist Maurice Duverger. Both men intended to describe the French Fifth Republic (established in 1958).

Ministry or department (also less commonly used secretariat, office, or directorate) are designations used by first-level executive bodies in the machinery of governments that manage a specific sector of public administration.

These types of organizations are usually led by a politician who is a member of a cabinet—a body of high-ranking government officials—who may use a title such as minister, secretary, or commissioner, and are typically staffed with members of a non-political civil service, who manage its operations; they may also oversee other government agencies and organizations as part of a political portfolio. Governments may have differing numbers and types of ministries and departments. In some countries, these terms may be used with specific meanings: for example, an office may be a subdivision of a department or ministry.

The Government of Ireland (Irish: Rialtas na hÉireann) is the executive authority of Ireland, headed by the Taoiseach, the head of government. The government – also known as the cabinet – is composed of ministers, each of whom must be a member of the Oireachtas, which consists of Dáil Éireann and Seanad Éireann. Ministers are usually assigned a government department with a portfolio covering specific policy areas although provision exists for the appointment of a minister without portfolio.

The taoiseach must be nominated by the Dáil, the House of Representatives, from among its members. Following the nomination of the Dáil, the president of Ireland formally appoints the taoiseach. The president also appoints members of the government on the nomination of the taoiseach and their approval by the Dáil. The taoiseach nominates one member of the government as tánaiste, the deputy head of government. Like the taoiseach, the tánaiste and the minister for finance must be members of the Dáil.

A private member's bill is a bill (proposed law) introduced into a legislature by a legislator who is not acting on behalf of the executive branch. The designation "private member's bill" is used in most Westminster system jurisdictions, in which a "private member" is any member of parliament (MP) who is not a member of the cabinet (executive). Other labels may be used for the concept in other parliamentary systems; for example, the label member's bill is used in the Scottish Parliament and the New Zealand Parliament, the term private senator's bill is used in the Australian Senate, and the term public bill is used in the Senate of Canada. In legislatures where the executive does not have the right of initiative, such as the United States Congress, the concept does not arise since bills are always introduced by legislators (or sometimes by popular initiative).

In the Westminster system, most bills are "government bills" introduced by the executive, with private members' bills the exception; however, some time is set aside in the schedule for reading such bills. They may be introduced by non-ministerial MPs from government-supporting parties (backbenchers), by members of opposition parties (frontbencher or backbencher), or by independents or crossbenchers. The Israeli Knesset has a long history of enacting private members' bills: a slight majority of the laws passed by it originated as private members' bills, and thousands more are introduced without being passed. In contrast, the Oireachtas (parliament) of the Republic of Ireland rarely passes private members' bills, with the overwhelming number of bills being passed being introduced by members of the cabinet.

A ministry of finance is a ministry or other government agency in charge of government finance, fiscal policy, and financial regulation. It is headed by a finance minister, an executive or cabinet position .

A ministry of finance's portfolio has a large variety of names around the world, such as "treasury", "finance", "financial affairs", "economy" or "economic affairs". The position of the finance minister might be named for this portfolio, but it may also have some other name, like "Treasurer" or, in the United Kingdom, "Chancellor of the Exchequer".
