1979 Nagapattinam by-election


On 17 June 1979 a by-election was held in for the Nagapattinam seat in the Lok Sabha. The by-election was called after the murder of the incumbent Communist Party of India parliamentarian S.G. Murugaiyan, one of three prominent communist leaders killed in the state of Tamil Nadu in 1979. The Nagapattinam constituency was reserved for Scheduled Castes.
By 1979 CPI had moved away from the Indian National Congress. The CPI candidate K. Murugaiyan had the support from the Dravida Munnetra Kazhagam and the Communist Party of India. The CPI candidate, himself a bonded labourer, had overwhelming support from the Dalit communities in the constituency.
The All India Anna Dravida Munnetra Kazhagam candidate M. Mahalingam had the support from the Congress. The Nagapattinam by-election was held simultaneously as a by-election in the Thanjavur Lok Sabha constituency. AIADMK supported the Congress candidate in Thanjavur, and AIADMK supremo M.G. Ramachandran toured both constituencies during the election campaign. Nevertheless the Congress leader Indira Gandhi only campaigned in Thanjavur.

Aftermath

The CPI hailed the by-election as a victory for left and democratic forces. However, the CPI state chief took a more cautious tone, stating that the by-election outcome "show that autocratic forces are still strong in Tamil Nadu". The head of the Pradesh Congress Committee bitterly accused M.G. Ramachandran of not having supported the party candidate in Nagapattinam sufficiently.
K. Murugayian lost the Nagapattinam seat in the subsequent 1980 Lok Sabha election to the DMK candidate Thanzai M. Karunanidhi.
