The Chepauk-Thiruvallikeni State Assembly constituency in Tamil Nadu is experiencing a nail-biting contest as Udhayanidhi Stalin (from the Dravida Munnetra Kazhagam, DMK) leads with 28,349 votes, closely followed by Selvam D from the Tamilaga Vettri Kazhagam (TVK) with 27,301 votes. This election marks a significant moment in Tamil Nadu's political history, with a 90.24% voter turnout reported by the Election Commission of India, a substantial increase from the 58.33% in the previous assembly elections in 2021. Udhayanidhi, the son of current Chief Minister M K Stalin, is aiming to retain his seat, having previously won in the 2021 elections. Meanwhile, the TVK, led by actor-turned-politician C Joseph Vijay, is showing a remarkable performance, leading in over 108 constituencies in the 234-member Assembly, indicating a potential shift in the state's long-standing political dynamics that have been dominated by the DMK and the All India Anna Dravida Munnetra Kazhagam (AIADMK). As the final results are awaited, the implications for government formation in Tamil Nadu remain significant.
