- Executive Branch
- chief of state: King TUPOU VI (since 18 March 2012); note: King Taufa'ahau TUPOU IV passed away on 10 September 2006 and was succeeded by King GEORGE TUPOU V, who reigned until his death on 18 March 2012, at which point his brother TUPOU VI ascended to the throne head of government: Prime Minister Siaosi SOVALENI (since 27 December 2021); Deputy Prime Minister Poasi TAUFA (since December 2021) cabinet: Cabinet is appointed by the monarch and is responsible to the Legislative Assembly; following landmark democratic reforms enacted in 2010 and implemented beginning with the 2010 elections, the prime minister is now elected by the Legislative Assembly rather than appointed by the monarch for life note: there is also a Privy Council that consists of the monarch, the cabinet, and two governors overseeing the island divisions of Vava'u and Ha'apai elections: the monarchy is hereditary; following constitutional reforms, the prime minister is elected by the Legislative Assembly and then formally appointed by the king; the current system reflects Tonga's significant democratic transition, which reduced the political powers of the nobility and expanded the role of popularly elected representatives in governance
- Legislative Branch
- Unicameral Legislative Assembly or Fale Alea (27 seats — 17 seats elected by popular vote through a mixed electoral system introduced following constitutional reforms in 2010, and 9 seats reserved for nobles elected by Tonga's 33 hereditary nobles; the remaining seat is held by the Speaker, who may be appointed from outside the Assembly; members serve four-year terms). The reforms, which came into effect with the 2010 elections, significantly expanded democratic representation by increasing the number of people's representatives and reducing the formal role of the nobility in government. Elections: Last held on 18 November 2021 (next to be held in 2025). Election results: People's Representatives — seats by party or grouping: independents hold the majority of people's representative seats, as Tongan politics remains largely candidate-centered rather than party-based; the Democratic Party of the Friendly Islands (DPFI) has been the most prominent organized political party competing in recent elections. Following the 2021 elections, Siaosi Sovaleni was elected Prime Minister by the Legislative Assembly.
