The alliance between the Dravida Munnetra Kazhagam (DMK) and the Indian National Congress has come to an end after more than two decades, marked by significant electoral struggles and internal tensions. The relationship faced challenges during seat-sharing negotiations, notably in 2011 and 2026, where both parties failed to secure favorable outcomes, leading to electoral losses. The DMK's leader, M. K. Stalin, expressed frustration over Congress leader Rahul Gandhi's lack of communication during crucial negotiations, signaling a breakdown in their previously perceived close relationship. Local Congress leaders felt marginalized by DMK functionaries, leading to resentment and calls for a new direction, including potential collaboration with the Tamil Nadu Vanniyar Katchi (TVK) party, led by actor Vijay. This shift raises concerns about the future of Tamil Nadu politics, with the BJP potentially benefiting from a fragmented opposition landscape. The historical rivalry between the DMK and Congress, particularly following the 1967 elections and the Emergency period, has now resurfaced, complicating the political scenario in the state as both parties navigate their futures without each other.
