Tensions have emerged between the Congress party and the Dravida Munnetra Kazhagam (DMK) following Congress's announcement to support actor Vijay's Tamizhaga Vetri Kazhagam (TVK) in forming the next government in Tamil Nadu. Vijay's impressive performance in the 2026 Tamil Nadu Assembly elections has led Congress to back him, with Congress MP Karti Chidambaram stating that the decision was made unanimously to support a 'secular change' in the state. However, the DMK has reacted strongly, accusing Congress of betrayal and labeling it a 'backstabber' for supporting a party they claim is aligned with the Bharatiya Janata Party (BJP). DMK spokesperson Saravanan Annadurai criticized Vijay for thanking Prime Minister Narendra Modi following his victory, questioning the integrity of the Congress's support. Congress has stipulated that its backing is conditional on the TVK excluding any communal forces that do not adhere to the Constitution of India. This political rift may have broader implications for alliances across the country, as the DMK warns that Congress's actions could create distrust among its other partners.
