Though born into a family that traditionally held the priestdom of the famous Vaithiyalingasamy Kovil in Aladipatti, he was strongly influenced by the rationalist movement spearheaded by Periyar and greatly enchanted with the silver-tongued oratory of
C. N. Annadurai and
M. Karunanidhi. These influences soon became his guiding forces and he entered the political movement even as a young student and actively participated in the "
Anti-Hindi agitation". His book "Hindi Egathipathiyam" is considered a treatise on the movement. He started his political career by unsuccessfully contesting in the Assembly elections from
Alangulam as a
Dravida Munnetra Kazhagam (DMK) candidate in
1962. He was later elected to the Assembly on two occasions in
1967 and
1971 as a DMK candidate. He was greatly responsible for the organisation of cooperatives for the beedi workers during this period. He also won Lok Sabha election in 1977 from Tirunelveli. He later joined the
Anna Dravida Munnetra Kazhagam and was elected to the Lok Sabha, from Tirunelveli and later
M. G. Ramachandran nominated him to the
Rajya Sabha from
Tamil Nadu in 1984. He also served as the leader of the AIADMK in the Rajya Sabha. During this tenure, he served as a member of the Joint Parliament Committee that probed the
Bofors scandal. He raised a dissent note on the report of the Joint Parliamentary Committee which examined the Bofors Scam, which was a death-knell to the Rajiv Gandhi government. Aladi Aruna's comment in the dissent note said "The son (Rajiv Gandhi) has surpassed mother (Indira Gandhi) in corruption and abuse of power". After the death of Ramachandran, he rejoined the DMK and was appointed its spokesperson. He was the first person to hold office as spokesperson in the DMK. He became a Law Minister of Tamil Nadu after winning the assembly election contesting as a DMK candidate in
1996. He was instrumental in the establishment of the law university in Chennai and setting up the High Court branch in Madurai, bringing a law college to Tirunelveli. ==Electoral performance ==
