General elections were held in Tonga on 18 November 2021. Following the death of Prime Minister ûAkilisi Pà Âhiva in 2019, the governing Democratic Party of the Friendly Islands (PTOA) fragmented and went into opposition. Finance Minister Pà Âhiva Tuûiûonetoa subsequently left the PTOA and formed the Tonga People's Party (PAK). He ascended to premiership after garnering the support of fellow PTOA defectors, independents and some of the nobles' representatives. Shortly before the election, the PTOA was divided into two factions: the Core Team, led by former Deputy Prime Minister SÃÂmisi Sika, and the People's Team, headed by Siaosi Pà Âhiva, the son of ûAkilisi Pà Âhiva.
Major campaign issues included government corruption and the COVID-19 pandemic. Prime Minister TuâÂÂiâÂÂonetoa and his allies did not promote the PAK during the campaign, reportedly due to the imprisonment of its deputy leader, âÂÂEtuate Lavulavu, for corruption. The two PTOA factions ran separate candidate lists, and despite receiving the most votes in numerous constituencies, the party only won three seats due to vote splitting between the groups. Both Sika and Pà Âhiva also lost their seats. Prime Minister Tuûiûonetoa was the only successful candidate from the PAK, while independents won 13 seats. No women were elected. Following the election, former Deputy Prime Minister Siaosi Sovaleni and former Finance Minister ûAisake Eke contested the parliamentary election for prime minister. Tuûiûonetoa initially ran, but later withdrew due to insufficient support and backed Eke. Sovaleni went on to defeat Eke, and he assumed office on 27 December. Three cabinet ministers later lost their seats after being found guilty in court of engaging in corruption during the election.
The 2017 snap election was called by King Tupou VI on the advice of the then parliamentary speaker, Sialeûataongo Tuûivakanà Â. Prime Minister âÂÂAkilisi Pà Âhiva was not consulted by the monarch, with whom he had a strained relationship. Tuûivakanà  stated that he had resorted to an early election, claiming that Pà Âhiva intended to transfer the powers of the monarch and privy council to cabinet. Pà Âhiva declined to challenge the monarch's decision, and his PTOA party went to secure a landslide victory, winning 14 of the 17 people's seats. Following the election, the Legislative Assembly re-elected Pà Âhiva as prime minister, receiving 14 votes. He defeated former Deputy Prime Minister Siaosi Sovaleni, the only other contender for the premiership, who received the support of 12 MPs. Pà Âhiva died in September 2019, and the PTOA began to fragment shortly after, with no clear successor emerging. Two individuals ran in the parliamentary vote to succeed Pà Âhiva, Acting Prime Minister SÃÂmisi Sika and Finance Minister Pà Âhiva Tuûiûonetoa, who left the party after Pà Âhiva's death and formed the Tonga People's Party (PAK). Tuûiûonetoa garnered the support of the nobles, independents and three fellow defectors from the PTOA, and went on to defeat Sika, whom the remaining members backed. As a result, the PTOA was pushed out of government and fell into opposition. Tuûiûonetoa's cabinet included three nobles, who were excluded under Pà Âhiva.
In December 2020, Sika submitted a no-confidence motion against Tuûiûonetoa. Deputy Prime Minister Sione Vuna Faûotusia supported the motion and subsequently resigned from cabinet. On 12 January 2021, the Legislative Assembly defeated the motion, with 13 MPs voting to strike it down and nine members, including the PTOA MPs, voting for it.
In June 2021, months before the election, Infrastructure and Tourism Minister ûAkosita Lavulavu and her husband, PAK deputy leader and former cabinet minister ûEtuate Lavulavu, were convicted of obtaining money on false pretences. The Supreme Court sentenced the couple to six years in prison.
The Legislative Assembly of Tonga has up to 30 members, of which 17 are directly elected by first-past-the-post voting from single-member constituencies. The island of Tongatapu has ten constituencies, Vavaûu three, Haûapai two and ûEua and the Niuas have one each. Nine seats are held by members of the nobility who elect representatives amongst themselves. The cabinet formed by a prime minister may include up to four members not elected to the Assembly, who then automatically become members of the legislature. Unless the monarch dissolves the Legislative Assembly early, members serve a four-year term.
Candidates and voters are required to be at least 21 years old and hold Tongan citizenship. Ineligible voters include those who have served a prison sentence of at least two years and individuals convicted of a criminal offence. To qualify, candidates are required to be eligible voters and present in Tonga for at least a three-month period within the six months before an election. Candidates running for a people's seat also require the signatures of at least 50 qualified electors from the constituency they contest and a deposit to be paid. Individuals subject to legal action for outstanding debt are ineligible to be contestants. Contestants for the people's seats were also required to undergo a legal clearance to qualify. The nobles, however, were exempt from this procedure. A total of 62,253 individuals were registered to vote in this election.
A total of 75 people's candidates were registered to contest the election. The total, however, later decreased to 72, after one candidate died and two others withdrew from the race. There were 12 female candidates, down from 16 in 2017. Amidst internal division and turmoil, the PTOA was split into two rival factions going into the election: the People's Board and the PTOA Core Team. Siaosi Pà Âhiva, the son of âÂÂAkilisi Pà Âhiva, led the People's Board, while former Deputy Prime Minister SÃÂmisi Sika headed the Core Team faction. Both factions fielded their own candidate lists, competing against one another. An informal bloc of independent candidates emerged, which was reportedly led by Education Minister Siaosi Sovaleni. According to a bloc member, the group's purpose was to help ensure a swift formation of a government, should all affiliated candidates secure a seat. The bloc also aimed to secure the support of some of the nobles' representatives.
Major issues during this election included the wide usage of illicit drugs, government corruption and the COVID-19 pandemic. Many candidates campaigned on their personal records. Prime Minister Tuûiûonetoa did not promote his PAK party during the election, which was also completely absent from his campaign platform and speeches. Many of his ministers instead ran as independents. Journalist Kalafi Moala suggested that the PAK's scarce presence during the campaign and its supporters' reluctance to promote it were likely due to the imprisonment of Deputy Leader Lavulavu. Prime Minister TuâÂÂiâÂÂonetoa and his allies campaigned primarily on infrastructure. Moala believed independent candidates had an overall advantage, citing the PTOA infighting and the PAK's scandals.
King Tupou VI issued the election writ on 2 September, while the parliamentary term formally ended on 16 September. Candidate nominations were open from 27 to 28 September, while voter registration closed on 3 November. Shortly before the election, Tongatapu was placed under a week-long lockdown due to a COVID-19 case, with candidates restricted from campaigning on the island. Election Supervisor Pita Vuki, however, announced that the election would not be delayed, stating that the Electoral Act did not permit an election postponement under those circumstances. A campaign blackout occurred on 17 November. On election day, polling stations for the people's seats were open from 9:00 to 16:00, while voting for the nobles' representatives took place in the morning. No overseas delegations were present in Tonga to observe the election, due to the COVID border restrictions. Some foreign diplomats present in the country, however, did oversee the electoral process.
The PTOA received the most votes in a many constituencies; however, due to vote-splitting between the rival factions' candidates, the party only secured three seats. Both faction leaders, Siaosi Pà Âhiva and SÃÂmisi Sika, lost their re-election bids. Prime Minister Tuûiûonetoa was the only successful candidate from his PAK party, while the other 13 people's seats were won by independent contestants. Nine of the victorious people's candidates and two of the noble MPs were newcomers, while ûAlipate Tuûivanuavou Vaea also returned to parliament after losing his seat in 2017. No women were elected, with incumbent MP Losaline Maûasi losing in Tongatapu 5. Female contestants received an overall lower combined vote share than in 2017. Voter turnout was around 62%, down from 67% in the previous election. The electoral commission conducted recounts in five constituencies, including the prime minister's, which were completed on 29 November. The recounts slightly altered the vote totals, but did not change any of the outcomes in these seats.
Following the election, three members of parliament declared their candidacies for the prime ministerial election: Prime Minister Tuûiûonetoa, former Deputy Prime Minister Siaosi Sovaleni and former Finance Minister ûAisake Eke. TuâÂÂiâÂÂonetoa later withdrew from the race, due to a lack of support in parliament, leaving Sovaleni as the frontrunner. Tuûiûonetoa subsequently endorsed Eke. During the parliamentary vote on 15 December, Sovaleni received 16 votes, defeating Eke, who garnered the support of 10 MPs. Fatafehi FakafÃÂnua was re-elected as speaker, as was his deputy, fellow HaâÂÂapai MP Havea Tuûihaûangana. The monarch formally appointed Sovaleni as prime minister on 27 December and unveiled his cabinet two days later. Included among his ministers was one woman, Fekitamoeloa ûUtoikamanu, who assumed the portfolios of foreign affairs and tourism, and became the sole female member of parliament. Sovaleni also selected one noble MP to serve in cabinet, Tonga Tuûiûafitu, who became the minister for lands and natural resources. The monarch formally opened parliament on 11 January 2022.
The election of three cabinet ministers, Deputy Prime Minister Poasi Tei, Finance Minister Tatafu Moeaki and Internal Affairs Minister Sangster Saulala, was voided by the Court of Appeal on 9 August 2022. The rulings followed the lodging of electoral petitions, alleging that the trio had engaged in corrupt practices, including bribery, during the election. The trio were formally unseated the following day, triggering by-elections in their constituencies. Electoral petitions against ûUhilamoelangi Fasi and Tevita Puloka were unsuccessful. Tuûiûonetoa's election was initially voided, but he successfully appealed the ruling and remained in parliament until his death in 2023.
