Sengottaiyan, who spent nearly fifty years in the AIADMK, was expelled from the party in October. He last won the Gobichettipalayam Assembly seat in 2021. Once a close supporter of former Chief Minister Jayalalithaa, he had earlier been removed from all organisational roles, including Organisation Secretary and District Secretary for Erode (Rural West).

He began his political career in the 1970s as the Panchayat President of Kullampalayam in Coimbatore, later becoming an MLA from Sathyamangalam in 1977. He also served multiple terms as a minister in Jayalalithaa’s cabinet. His entry into TVK is likely to strengthen the party’s organisational depth as the state prepares for elections next year.
