Australia Government#
National level#
The federal government of Australia operates as a constitutional monarchy with a parliamentary system, comprising the executive and legislative branches.
Executive branch#
The Prime Minister, while not a constitutional position, plays a pivotal role in the executive branch. Appointed by the Governor-General, the Prime Minister is usually the leader of the largest party in the House of Representatives, although this is not a requirement. The Governor-General represents the Sovereign and performs various ceremonial duties. The Prime Minister leads the Cabinet and the government, steering national policy and administration. The executive branch also includes ministers who head specific government departments and are usually drawn from the Parliament. The Governor-General is not maintained by Melissa.
Legislative branch#
The Parliament of Australia is bicameral, consisting of the House of Representatives and the Senate. The House of Representatives has 151 Members of Parliament (MPs) elected from single-member electoral divisions. The number of MPs can change with electoral adjustments. The House must be dissolved within three years from its first meeting, often earlier. The Senate comprises 72 state senators (12 from each state) serving staggered six-year terms, with half elected every three years. In the case of a double dissolution, all senators are up for election, and terms are adjusted to reestablish the staggered system. Additionally, there are four territorial senators elected at the same time as the House of Representatives, serving concurrent terms.
State/Territorial level#
Executive branch#
Each state has a Governor appointed by the Sovereign, performing largely ceremonial duties. The Premier is the head of the government in each state, appointed by the Governor and typically the leader of the majority party in the Legislative Assembly. The Premier leads the executive branch of the state government, directing policy and administration. In the territories, the Chief Minister holds a similar role, elected by members of the Legislative Assembly in the Australian Capital Territory and appointed by the Administrator in the Northern Territory. The Administrator, appointed by the Governor-General, performs ceremonial duties in the Northern Territory. The individual state Governor are not maintained by Melissa.
Legislative branch#
State parliaments generally consist of two houses: the Legislative Council (upper house) and the Legislative Assembly (lower house), except for Queensland, which has a unicameral legislature. The Legislative Assembly is responsible for proposing and passing legislation, while the Legislative Council reviews and amends proposed laws. In the territories, the legislative branch consists of a single Legislative Assembly, which functions similarly to the lower houses of state parliaments. Members of these assemblies are elected to represent the people of their respective states or territories, contributing to the legislative process and governance.
Canada Government#
Canada’s national government operates as a constitutional monarchy and a parliamentary democracy.
National level#
Executive branch#
The executive branch is headed by the monarch, represented domestically by the Governor General, who performs ceremonial duties and acts on the advice of the Prime Minister and the Cabinet. The Prime Minister, as the head of government, leads the executive branch and is supported by a Cabinet composed of ministers typically selected from the House of Commons.
Legislative branch#
The legislative branch consists of a bicameral Parliament, which includes the elected 338 members of House of Commons and the appointed 105 members of Senate. Members of the House of Commons, known as Members of Parliament (MPs), are elected, while Senators are appointed on the advice of the Prime Minister. Senators are subject to a mandatory retirement age of 75.
Provincial/Territorial level#
Canada’s provincial and territorial governments operate within a framework similar to the federal House of Commons. They are tailored to local needs; and which are unicameral bodies.
Executive branch#
The head of the provincial government is the Premier, a role analogous to the Prime Minister at the federal level and supported by a cabinet of ministers. While territories have Commissioners appointed by the federal government. This decentralized structure allows provinces and territories to address local needs and preferences within the framework of Canada’s Constitution.
Legislative branch#
The provincial legislatures pass laws on matters of regional importance, such as education, health, and transportation, while territories have similar powers but with more federal oversight.
Local level#
Canada’s local government structure consists of municipalities, which include cities, towns, villages, and rural districts. These local governments are established by provincial and territorial legislation and vary in size and function. Municipalities are typically governed by elected councils, which include a mayor or reeve and councilors. The mayor acts as the executive head, leading the council and representing the municipality in ceremonial functions. Local governments are responsible for delivering essential services such as water supply, waste management, local road maintenance, public transit, and zoning and land use planning. They also manage recreational facilities, libraries, and local police and fire services. Funding for municipalities primarily comes from property taxes, user fees, and provincial and federal grants. This local governance structure allows for responsive and community-specific decision-making, ensuring that local needs and priorities are addressed effectively.

Germany Government#
Germany operates as a federal parliamentary republic.
National level#
Executive branch#
The head of the German executive branch is the Federal Chancellor, who leads the federal government. The Federal President serves as head of state with largely ceremonial duties. The Chancellor appoints federal ministers who head the various federal ministries and form the Federal Cabinet. The Chancellor is elected by the Bundestag and requires a majority vote. While members of this chamber are generally not maintained by Melissa, we do maintain the Federal Chancellor, who is part of the Bundestag, and other ministers in the cabinet could also technically be members of the Bundestag.
Legislative branch#
Federal lawmaking in Germany falls to a bicameral system comprised of two chambers:
Bundestag (Federal Parliament) - The lower house with 630 members currently (minimum 598) elected every 4 years through mixed-member proportional representation from 299 constituencies.
Bundesrat (Federal Council) - The upper house with 69 members appointed by state governments to represent state interests at the federal level. It operates as a continuous body with no fixed terms.
Together, these chambers work to pass federal laws, with the Bundestag having primary legislative authority and the Bundesrat representing state interests.

United Kingdom Government#
Federal Government#
The United Kingdom has a multinational government, composed of four distinct countries: England, Scotland, Wales, and Northern Ireland. Each of these countries has its own devolved government, while the Government of the United Kingdom acts as a central executive authority for the entire region. The United Kingdom’s government structure at the national level is a constitutional monarchy with a parliamentary democracy.
Executive branch#
The executive branch of the United Kingdom is headed by the Prime Minister, who is the leader of the majority party in the House of Commons, the lower house of Parliament. The Prime Minister is supported by the Cabinet, composed of senior ministers responsible for various government departments. The Prime Minister is appointed by the Monarch, who serves as the ceremonial head of state. The Cabinet members are appointed by the Prime Minister, and are conventionally chosen from the two houses of Parliament. While the Monarch holds a symbolic and ceremonial role, the executive power is vested in the Prime Minister and the Cabinet, who are responsible for the administration and implementation of government policies.
Legislative branch#
The legislative branch is a bicameral system consisting of the House of Lords and the House of Commons.
The House of Lords, which includes approximately 800 appointed life peers, bishops, and hereditary peers, acts as a revising chamber, reviewing and suggesting amendments to legislation proposed by the Commons. Together, these branches work to create, implement, and uphold the laws and policies governing the UK. Members of this appointed chamber are not maintained by Melissa.
The House of Commons is composed of 650 Members of Parliament (MPs) elected by the public from constituencies across all four countries. It holds significant legislative power, including the authority to pass laws and allocate funds.

Municipal Chambers#
The Greater London Assembly (GLA) is a key component of the Greater London Authority, responsible for overseeing the strategic governance of London.
Established in 2000, the GLA comprises the Mayor of London and the London Assembly, the latter consisting of 25 elected members who represent different areas and political parties.
The primary role of the London Assembly is to scrutinize the activities and decisions of the Mayor, ensuring accountability and transparency in the execution of policies and the allocation of resources. The Assembly reviews and provides input on issues such as transportation, housing, economic development, and environmental policies, aiming to enhance the quality of life for London’s diverse population. Additionally, the GLA works to promote sustainable development and address the city’s long-term challenges, making it a vital institution in the governance of the UK’s capital.
Northern Ireland#
Northern Ireland is variously known as a country, region, or province of the United Kingdom. Its government operates as a devolved administration, meaning it has the authority to legislate in areas not explicitly reserved to the Parliament of the United Kingdom. The devolution of powers allows Northern Ireland to address its unique needs and circumstances through local governance.
The Northern Ireland Assembly is the legislative body consisting of 90 Members of the Legislative Assembly (MLAs). These members are elected using the single transferable vote (STV) system, with each of the 18 constituencies returning five members. Elections are held every five years, although they can occur earlier if necessary. The Assembly has a wide range of powers transferred from the UK government, enabling it to legislate on issues such as health, education, and justice.
Scottland#
The Scottish Government operates within the framework of a devolved system, legislating in areas not reserved for the UK Parliament. The legislative branch is the Scottish Parliament, consisting of 129 Members of the Scottish Parliament (MSPs). These MSPs are elected for five-year terms, with 73 representing geographic constituencies and 56 elected from “additional member” regions. This structure ensures a mix of direct representation and proportional representation. MSPs serve five-year terms.
The executive branch is led by the First Minister, who is nominated by the MSPs and formally appointed by the Sovereign. While technically any MSP can be appointed, the First Minister is almost always the leader of the largest party in the Scottish Parliament. The First Minister does not have a fixed term and serves at the pleasure of the Sovereign, contingent upon maintaining the confidence of the Scottish Parliament. The First Minister appoints other Ministers from the Parliament, forming a Cabinet to lead the Scottish Government. This Cabinet is responsible for executing government policies and administering public services.
Wales#
Wales has a devolved government, meaning it legislates in areas not reserved for the UK Parliament. The Welsh Parliament, or Senedd Cymru, is composed of 96 Members of the Senedd (MSs) from the 2026 election onward. MSs are elected from 16 constituencies, with six Members elected from each constituency. Voters cast one vote for either a political party or an independent candidate under a closed-list proportional representation system. Political parties may put forward ranked lists of candidates in each constituency, and seats are allocated using the D’Hondt formula. Independent candidates stand as individuals and, if they win enough votes, may be elected to one of the constituency’s six seats. From 2026, MSs serve four-year terms, with the next ordinary election after 2026 scheduled for 2030. Until 2020, this body was known as the National Assembly for Wales. Typically, the largest party in the Senedd forms the Welsh Government.
The Welsh Government, or Llywodraeth Cymru, is led by the First Minister, who is nominated by the Senedd and appointed by the Monarch. The First Minister, usually the leader of the largest party or the person best able to command support in the Senedd, selects other Ministers, forming the Cabinet. The First Minister chairs the Cabinet, which includes Ministers who attend Cabinet meetings and Deputy Ministers who do not. The Counsel General, who is appointed by the Monarch on the recommendation of the First Minister, also attends Cabinet meetings.

United States Government#
The United States Government has three branches: executive, legislative, and judicial. Melissa maintains two of these: the Executive and Legislative chambers, which include; elected and appointed officials from the national government, as well as state and local level governments.
National level#
Executive branch#
The head of the U.S. executive branch is the President, who resides in the White House. The Vice President assist the President, the executive office manages day-to-day operations. The President also appoints the heads of the 15 executive departments, which make up the Cabinet, to oversee specific areas like defense or education. These appointments require confirmation by the Senate.
Legislative branch#
Lawmaking at the Federal Level in the United States falls to Congress, a bicameral legislature comprised of two chambers:
The Senate, the upper house, has 100 members with two representatives from each state regardless of population size.
The House of Representatives, the lower house, has 435 members with the number of representatives apportioned among the states based on their total population.
Together, these two chambers work to pass laws, approve treaties, and confirm presidential appointments.
Committee#
A subgroup of the House or Senate established for the purpose of considering legislation, conducting hearings and investigations, or carrying out other assignments as instructed by its respective Chamber.
State level#
Executive branch#
At the state level, the Executive branch is headed by the governor, who is elected directly by the populace. Along with lieutenant governor, there are a varied number of executive roles per state (such as the attorney general, secretary of state, auditor, commissioners, etc.) who could be appointed by the Governor or elected by the populace.
Legislative branch#
State legislative branches mimic those at the Federal level, and also consist of upper and lower chambers; often a Senate, and a House of Representatives, House of Delegates, or Assembly. These bodies have the power to make laws on topics not granted to the federal government. The structure of state governments varies significantly. For example, Nebraska has a unicameral legislative body (1 chamber instead of two). The exact names, dates, term lengths, term limits, electoral systems, number of members and other details are determined by an individual state’s laws.
Local level#
Local level governments in the United States also have executive and legislative bodies. Though these too vary greatly from region to region, they generally, local government two tiers: counties and municipalities. There are a variety of legislative structures used in local governments, including boards of county commissioners, and city and town councils.
