Indian National Congress,
Communist Party of India,
Forward Bloc,
Praja Socialist Party,
Socialist Party,
Congress Reform Committee (Indian National Democratic Congress), and
Dravida Munnetra Kazhagam (DMK) were the major parties contesting this election. This was the first election contested by the DMK since its formation in 1949. The decision to contest elections was taken in 1956 at the party's Trichy conference. The party fielded its candidates in 8 parliamentary and 117 assembly seats as independents since it was not an officially recognised party. The increased Tamilian character of the Congress party after the appointment of
K. Kamaraj, a non-Brahman, as Chief Minister of Tamil Nadu, robbed DMK of its main electoral plank as the sole proponent of Tamil nationalism. It increasingly changed its focus to economic issues and the slower industrialization of the South as an election issue. The DMK election manifesto had a socialist image, and the creation of
Dravida Nadu became a side issue as it implicitly accepted the prevailing constitutional order.
Periyar E. V. Ramasamy issued a statement in support of K. Kamaraj before the commencement of the election. In October 1956, the central executive of
Dravidar Kazhagam resolved to support K. Kamaraj. Since Mr. Kamaraj has done his best to serve the Tamilians, since he has changed Acharyar's educational system designed to perpetuate the caste system, since he has conferred many jobs and many benefits on Tamilians in the educational and other spheres and since the Brahman and DMK people are trying to oust him from power, it has become the duty of all Tamilians to support Mr. Kamaraj and his followers in the election K. Kamaraj accepted the support of Dravidar Kazhagam and said if the Kazhagam canvassed votes for him out of their own free will, he could not possibly tell them he did not want their votes. He also made it clear that the Congress party cannot support a party that is communal in nature, and he did not in any way share E. V. Ramasamy's views.
K. Kamaraj's decision to accept support and provide candidature to some former members of
Dravidar Kazhagam caused division within Congress, resulting in a new party called the Congress Reform Committee (CRC). Though the party was created in the last moment, it fielded candidates in 12 parliamentary and 55 assembly seats.
Forward Bloc Leader
Pasumpon Muthuramalinga Thevar accused the ruling Congress party of engaging in vote-buying practices by distributing money to voters and urged the electorate to reject such inducements, describing them as immoral. He pointed out that people willingly spent ₹2 to ₹5 to witness
Jallikattu, and argued that accepting ₹5 or ₹10 in exchange for exercising one’s franchise was wrong. ==Voting and results==
