In 1974, Kumaratunga started his political career in the
Lanka Sama Samaja Party (LSSP). He later joined the
Sri Lanka Freedom Party (SLFP) and became its vice secretary. In 1977, he ran unsuccessfully for the
Katana seat in
Parliament. Five years later, he was active in the 1982 presidential campaign of
Hector Kobbekaduwa. After the election, he was accused of being a
Naxalite and jailed under the emergency regulations of President
J. R. Jayewardene, but he was never charged. He ran as the SLFP candidate in a by-election in
Mahara in 1983 and was threatened by
United National Party (UNP) supporters. An attempt was made on his life, and one of his friends was killed. Kumaratunga won the first vote count, and a recount was ordered. At that point, a blackout occurred at the counting centre. By the time electricity was restored, the UNP candidate had recorded a victory by a few votes. The opposition alleged that someone had "eaten some of Vijaya's votes to ensure UNP victory". On 22 January 1984 he founded the
Sri Lanka Mahajana Party (SLMP) and became its first national organizer, which campaigned for peace in the
Sri Lankan Civil War. Under his new party, he contested a
Minneriya by-election and finished second, behind the UNP candidate—relegating his old party, SLFP, to third place. The SLMP went on to contest several other by-elections, including in
Kundasale and
Habaraduwa, but did not live up to expectations. In 1988, the SLMP reached an agreement with several other left-wing parties—including the LSSP,
Nava Sama Samaja Party (NSSP),
Sri Lanka Communist Party, and
Eelam People's Revolutionary Liberation Front (EPRLF)—to form the
United Socialist Alliance (USA). A few days prior to the establishment of the new alliance, Kumaranatunga was assassinated. The agreement was signed by party leaders at his funeral. The USA won a large number of seats in the newly formed provincial councils in an election boycotted by the main opposition SLFP. However, in the
1988 presidential election, the USA candidate,
Ossie Abeygunasekera, finished in last place. In the 1989 parliamentary elections, USA candidates won three seats, but none of the winners represented the SLMP. == Personal life ==
