The politics of Tuvalu takes place in a framework of a parliamentary representative democratic monarchy, whereby the monarch is the head of state, represented by the governor-general, while the prime minister is the head of government. Executive power is exercised by the government.

The Constitution of Tuvalu states that it is "the supreme law of Tuvalu" and that "all other laws shall be interpreted and applied subject to this Constitution"; it sets out the Principles of the Bill of Rights and the Protection of the Fundamental Rights and Freedoms. In 1986 the Constitution adopted upon independence was amended in order to give attention to Tuvaluan custom and tradition as well as the aspirations and values of the Tuvaluan people. The changes placed greater emphasis on Tuvaluan community values rather than Western concepts of individual freedom. The Constitution of Tuvalu Act 2023, further addressed the role of Tuvaluan culture, and also referred to the climate crisis, and Tuvalu’s statehood and national boundaries.

Tuvalu follows the Westminster system of representative democracy although Tuvalu is a non-partisan democracy and elections in Tuvalu take place without reference to formal political parties. At the date of independence there were 12 members of the Parliament of Tuvalu. Amendments to the Electoral Provisions (Parliament) Act in 1999 and 2000 increased the membership of parliament to 15 MPs. The Electoral Provisions (Parliament) Amendment Act 2019 increased the number of elected representatives for the electorate of Nukulaelae to become 2 MPs. So that each of the 8 island electorates is represented by 2 MPs, with Niulakita being represented by the MPs from Niutao.

The 16 members of the current parliament are elected from eight two-seat constituencies via plurality block voting.

Tuvaluans participated in the political institutions of the Gilbert and Ellice Islands Colony during the transition to self-determination. A referendum was held in December 1974 to determine whether the Gilbert Islands and Ellice Islands should each have their own administration.Nohlen, D, Grotz, F & Hartmann, C (2001) Elections in Asia: A data handbook, Volume II, p831 As a consequence of the referendum the Gilbert and Ellice Islands colony ceased to exist on 1 January 1976 and the separate British colonies of Kiribati and Tuvalu came into existence.

In 2008 Tuvaluans rejected a constitutional referendum that proposed replacing the Queen of Tuvalu, with an elected president as the head of state.

|Governor-General |Temukisa Auina Penehuro Hauma |30 September 2026 |- |Prime Minister |Feleti Teo |Independent |26 February 2024 |} —as the of Tuvalu—is the head of state, represented by the governor-general, who is appointed by the King on advice of the Prime Minister of Tuvalu. The prime minister is elected by the members of the parliament. The members also elect the Speaker of the Parliament of Tuvalu who is the presiding officer of the parliament. The ministers that form the cabinet are appointed by the governor-general on the advice of the prime minister. The Attorney-General sits in parliament, but does not vote: the parliamentary role of the Attorney-General is purely advisory. The current Attorney-General is Laingane Italeli Talia.

The Office of the Prime Minister supports the prime minister and the deputy prime minister and also has responsibility for the public service, the police, immigration, broadcasting and media. The Cabinet of Tuvalu consists of the Prime Minister and eight ministers, who are allocated the portfolios made up of the government departments that each minister supervises.

During the governments of Bikenibeu Paeniu, Ionatana Ionatana, and Faimalaga Luka, members of parliament who were not ministers were appointed to positions described variously as ‘Special Ministerial Advisers” and “Parliamentarians with Special Responsibilities” and, in one case, as Chairman of a Public Service Reform Committee. A decision of the High Court of Tuvalu in 2003 determined that “Cabinet did not have the power to make these appointments and the purported use of such a power was unlawful.”

Judicial branch

Tuvalu maintains an independent judiciary consisting of a High Court, Magistrates Court on Funafuti and Island Courts and Lands Courts on each island. Appeals in relation to land disputes are made to the Lands Courts Appeal Panel. Appeals from the Island Courts and the Lands Courts Appeal Panel are made to the Magistrates Court, which has jurisdiction to hear civil cases involving up to $10,000. The superior court is the High Court of Tuvalu as it has unlimited original jurisdiction and hears appeals from the lower courts. The senior judicial officer is the Chief Justice of Tuvalu. Rulings of the High Court can be appealed to the Court of Appeal of Tuvalu. From the Court of Appeal, there is a right of appeal to His Majesty the King in Council, i.e., the Privy Council in London. No cases have been filed from Tuvalu in the Judicial Committee of the Privy Council yet, but it is available as an option.

The law of Tuvalu comprises the Acts voted into law by the Parliament of Tuvalu and statutory instruments that become law; certain Acts passed by the Parliament of the UK (during the time Tuvalu was either a British protectorate or British colony); the common law; and customary law (particularly in relation to the ownership of land).

Legislative branch

The legislative branch is the unicameral Parliament of Tuvalu or Palamene o Tuvalu has 16 members, elected for a four-year term in 8 double-seat constituencies, so that each of the 8 island electorates is represented by 2 MPs, with (Niulakita is represented by the MPs from Niutao). During the time that Tuvalu was a British dependency, the parliament was called the House of Assembly or Fale I Fono.

Ombudsman

In 2014, the office of the Chief Ombudsman was established, with the appointment of Sa'aga Talu Teafa. The primary role of the Chief Ombudsman is to work to achieve good governance through the enforcement of the Leadership Code Act.

Democratic values in Tuvalu

Democratic, non-partisan politics

Democratic values in Tuvalu are strong with free elections every 4 years by universal adult suffrage. There are no formal political parties so all candidates are non-partisan, and election campaigns are largely on the basis of personal/family ties and reputation. Tuvalu has "about 6,000 eligible voters" – a little over half the country's population., Agence France Presse, 16 September 2010."Tuvalu completes voting in national elections", Radio Australia, 16 September 2010.

Members of parliament have very close ties to the island they represent. Often the northern islands in the country compete against the southern islands with the center holding the balance of power. Traditional chiefs also still play a significant role in influencing island affairs, particularly on the outer islands. A long-held distinction between chiefs and commoners is slowly disappearing, and chiefs are now more often selected on merit rather than by birth.

Te Kakeega II is the statement of the national strategy for the sustainable development of Tuvalu, with goals intended to be achieved in the period 2005 to 2015. After consultations on each islands the National Summit on Sustainable Development (NSSD), was held at the Tausoalima Falekaupule in Funafuti from 28 June to 9 July 2004.Tausoalima means "hand of friendship" and Falekaupule, means traditional island meeting hall. The meeting resulted in the Malefatuga Declaration,Malefatuga is the area bounded by the Funafuti lagoon foreshore and the Fetu Ao Lima Church ("Morning Star"), where the Tausoalima is located. The old meaning of malefatuga is "challenge", the place where conflicts were resolved. Its modern usage is "place of identity and confidence, where good deeds are recorded". which is the foundation of Te Kakeega II.

In November 2020 the name "Te Kakeega” was replaced by “Te Kete” which is the name of a domestic traditional basket woven from green or brown coconut leaves. Symbolically, “Te Kete” has biblical significance for Tuvaluan Christian traditions by referencing to the basket or the cradle that saved the life of Moses.

Representation of women

Throughout the history of the Parliament of Tuvalu three women have been elected: Naama Maheu Latasi, from 1989 to 1997; and Pelenike Isaia who was elected in a by-election in 2011, serving until the 2015 general election; and Dr Puakena Boreham was elected to represent Nui in the 2015 general election, serving until the 2024 general election.

The under-representation of women in the Tuvalu parliament was discussed during a consultation entitled "Promoting Women in Decision Making" was held in Funafuti in May 2010. The outcome was a recommendation for the introduction of two new seats, to be reserved for women."Women Need Support to Overcome Barriers Entering Parliament", Solomon Times, 11 May 2010 The Tuvaluan Ministry for Home Affairs, which has responsibility for women's affairs, stated that steps would be taken to consider the recommendation."Support for introducing reserved seats into Tuvalu Parliament" , Pacific Islands Forum Secretariat, 13 May 2010

The frequent use of the motion of non-confidence in the prime minister

Tuvalu does not face serious governance issues. The frequent use of the parliamentary vote of no confidence, engendering many changes of government in relatively short periods, has sometimes been on issues which reflect on the relations between personalities rather than on pressing national issues. The apparent reasons for the resort to motions of no confidence in the prime minister in the period 1999 to 2004 were: the PM straying from policies supported by the majority caucus; claims that the PM was inefficient or ineffective; and accusations of corruption in making appointments.

During this period of time the terms of the prime minister were short. Bikenibeu Paeniu resigned as prime minister following the vote on a motion of no confidence on 27 April 1999. Ionatana Ionatana was elected as prime minister. After the death of prime minister Ionatana on 8 December 2000, Lagitupu Tuilimu was acting prime minister from 8 December 2000 to 24 February 2001. Faimalaga Luka became the prime minister on 24 February 2001 until he was replaced by Koloa Talake after a vote of no confidence on 14 December 2001. Koloa Talake was appointed prime minister until he was voted out of office as a result of the vote at the 2002 Tuvaluan general election.
