In most elections, no one party has won an absolute majority of seats and so usually parties must work with each other to formcoalition governments. The one exception is the 1989 election, when thePeople's Alliance Party (PAP) led by Solomon Mamaloni did win an absolute majority. However, in late 1990, Mamaloni broke away from thePAP and continued ruling in a coalition government until the 1993 election.
Many parties are established immediately prior to an election and most are very short-lived. Some will achieve no parliamentary representation and dissolve within a year. Others will achieve parliamentary representation but, having served their purpose, are then discarded.
The most enduring political parties in the Solomon Islands are thePAP and theSolomon Islands United Party, founded in 1979 and 1980, respectively. ThePAP has led three governments and been in coalition in at least three more. The United Party led two governments in the 1980s however its representation has waned in recent years and after the 2006, it no longer had any parliamentary representatives.
