Prime Minister of Tonga

The prime minister of Tonga is the head of government of Tonga. Tonga is a monarchy with the king, currently Tupou VI, former prime minister, as head of state. The current prime minister is Fatafehi Fakafānua, who has served since 18 December 2025. Fakafānua was elected by the Legislative Assembly following the 2025 general election.
The office of prime minister was established by the Constitution of 1875, whose article 51 stipulates that the prime minister and other ministers are appointed and dismissed by the king.
The prime minister is assisted by the deputy prime minister.

2000s democratisation

During the 2000s, the country experienced an increase in democratisation. In March 2006, King Tāufaʻāhau Tupou IV appointed Feleti Sevele, a moderate member of the Human Rights and Democracy Movement, as prime minister. Sevele was the first commoner to hold this post since Shirley Waldemar Baker in 1881. All the prime ministers since Baker had been members of the nobility, or even the royal family.
In July 2008, King George Tupou V announced more substantial democratic reforms. He would abandon the essential part of his executive powers, and would henceforth follow the custom of monarchies such as the United Kingdom, exercising his prerogatives only with the prime minister's advice. In addition, he would no longer appoint the prime minister anyone he wished, but would appoint a member of the Legislative Assembly to be elected by the Legislative Assembly.
