On 14 May 1972 the ACTC, ITAK, Ceylon Workers' Congress, Eelath Thamilar Otrumai Munnani and All Ceylon Tamil Conference formed the Tamil United Front, later renamed Tamil United Liberation Front (TULF).[8][9][10][11] Sivasithamparam was the TULF's candidate in Vavuniya at the 1977 parliamentary election and was re-elected.[12] Sivasithamparam and all other TULF MPs boycotted Parliament from the middle of 1983 for a number of reasons: they were under pressure from Sri Lankan Tamil militants not to stay in Parliament beyond their normal six-year term; the Sixth Amendment to the Constitution of Sri Lanka required them to swear an oath unconditionally renouncing support for a separate state; and the Black July riots in which up to 3,000 Tamils were murdered by Sinhalese mobs. After three months of absence, Sivasithamparam forfeited his seat in Parliament on 5 October 1983.[13]
On 30 September 1983 the Sri Lankan Army attacked Sivasithamparam's Madukulam farm, beating to death the farm manager Nadarajah and burning his body.[14] Fearing for his life, Sivasithamparam fled to India.[14] He later migrated to Canada where he died on 9 November 1992.[1]
