The PAP won a landslide victory in the 1989 elections, taking 23 of the 38 seats and Mamaloni became prime minister again. The 1993 elections saw the party reduced to nine seats as the Solomon Islands Government of National Unity, Reconciliation and Progress Party (SIGNUR) won 20. However, SIGNUR leader Francis Billy Hilly lost a vote of no-confidence in 1994 and Mamaloni was elected prime minister in his place. The PAP won only seven seats in the 1997 elections, resulting in Mamaloni returning to being Leader of the Opposition, a post he held until his death in 2000.
The party won 20 of the 50 seats in the 2001 elections, becoming the largest party in Parliament. The PAP's Allan Kemakeza became prime minister. In the 2006 elections, the party was reduced to three seats in a Parliament dominated by independents. It won two seats in the 2010 elections,[2] and three in the 2014 elections.
