During the previous general election held in 2006, the ruling Human Rights Protection Party won a landslide victory, winning 33 seats. The opposition
Samoan Democratic United Party (SDUP) secured ten seats, and independents won the remaining six. The SDUP later lost one seat due to an electoral petition. Later that year, in August 2006, the SDUP removed its leader,
Le Mamea Ropati, and replaced him with Deputy Leader
Asiata Saleimoa Vaai. The SDUP then fragmented and led to the departure of two MPs from the party, including Le Mamea Ropati. As a result, the SDUP's recognition as a parliamentary party ceased because it fell below the eight-seat threshold, and the parliament classified the party's remaining MPs as independents. On 11 May 2007, long-serving O le Ao o le Malo (head of state) Susuga
Malietoa Tanumafili II died. Parliament unanimously voted for
Tui Ātua Tupua Tamasese Efi, a member of the
Council of Deputies, former prime minister and son of former Co-Head of State
Tupua Tamasese Meaʻole, to succeed Malietoa. In September 2009, the government switched the country from right to left-hand driving to enable less costly vehicle imports from Australia and New Zealand. The change was controversial as most vehicles were on the left-hand drive, generating one of the largest protests in Samoan history. The same month, Samoa was devastated by an
earthquake and tsunami that claimed the lives of 158 people in the country. The prime minister faced criticism for allegedly mishandling relief funds. Eleven opposition MPs from the SDUP and independents formed the Tautua Samoa Party in 2008 to provide parliamentary opposition to the HRPP. Nine members of parliament subsequently aligned themselves with the new party. However, in 2009, speaker of parliament,
Tolofuaivalelei Falemoe Leiʻataua, declared their seats vacant and ordered by-elections to take place. The speaker argued the TSP members had broken parliamentary protocol by joining a new party during the legislative session. But the Supreme Court later ruled the speaker's decision to be unlawful, cancelling the by-elections and restoring the TSP MPs. The following year, parliament passed an amendment forbidding MPs from changing parties; those who would change their affiliation would have to run in a by-election to retain their seat. After the amendment's passage, only three MPs remained official TSP members and competed in subsequent by-elections; one member successfully retained his seat unopposed, while another secured a narrow win. Former Party Chair
Lealailepule Rimoni Aiafi was narrowly defeated by an HRPP member. In September 2010, the Samoa Party merged into the TSP. Feo Nemaia Esau, the Samoa Party's president, said the purpose of the merger was to strengthen the opposition. The TSP initially intended to refrain from electing a party leader until after the election to choose one of the successful parliamentary candidates. However, this prompted Prime Minister Malielegaoi to describe the TSP as a "headless monster" and he challenged the party to select a leader before the election. The party subsequently elected
Vaʻai Papu Vailupe, son of former prime minister
Vaai Kolone, as leader in December 2010. == Electoral system ==
