The Dravida Munnetra Kazhagam (DMK) has announced that it will not participate in the INDIA bloc meeting scheduled in New Delhi on June 8, marking a significant escalation in its growing rift with the Congress. The decision comes after senior DMK leader and Tamil Nadu Opposition Leader Udhayanidhi Stalin accused the Congress of betraying the party by supporting actor Vijay’s Tamilaga Vettri Kazhagam (TVK) following the recent Tamil Nadu Assembly elections.

The latest development signals a major political shift in Tamil Nadu and raises fresh questions about the future of opposition unity at the national level. Addressing a thanksgiving meeting in Chennai’s Chepauk-Triplicane constituency on Thursday, Udhayanidhi said the DMK would not forget what he described as Congress’ “betrayal” after nearly two decades of political partnership.

According to Udhayanidhi, several Congress legislators who won elections as part of the DMK-led alliance later extended support to TVK, a move that the DMK views as a breach of trust. He also pointed out that none of the victorious Congress MLAs visited the DMK leadership after the election results, further deepening tensions between the two parties.

Alliance Under Strain

The fallout has already resulted in visible political distancing. In May, the DMK sought a separate seating arrangement in the Lok Sabha, formally requesting that its MPs no longer be seated alongside Congress members. DMK leader Kanimozhi wrote to Lok Sabha Speaker Om Birla, stating that the changing political circumstances warranted a revised arrangement.

The latest decision to skip the INDIA bloc meeting is being viewed as another strong signal that relations between the two parties have deteriorated significantly. The June 8 meeting is expected to bring together leaders from several opposition parties, including Congress, Trinamool Congress and Samajwadi Party, to discuss future political strategies.

TVK's Rise Alters Political Equations

The emergence of actor-turned-politician Vijay’s TVK has reshaped Tamil Nadu’s political landscape. Formed in 2024, the party delivered a remarkable performance in the Assembly elections, securing 108 seats and emerging as a major force in the state.

The Congress decision to support TVK after the election results appears to have triggered the current conflict. DMK leaders argue that the move effectively undermined the alliance that had worked together during the election campaign.

Political analysts believe the development could have wider implications for opposition politics, especially at a time when regional parties are reassessing their relationships within the INDIA bloc.

From Partnership to Political Break

The Congress-DMK relationship has experienced several phases over the decades. While the two parties first collaborated during the early 1970s under the leadership of former Prime Minister Indira Gandhi and former Tamil Nadu Chief Minister M. Karunanidhi, the alliance later fractured after the assassination of Rajiv Gandhi in 1991.

The partnership was revived in 2004 when the DMK exited the NDA and joined hands with Congress. The alliance went on to achieve significant electoral success, including a near sweep in the 2004 and 2019 Lok Sabha elections and victory in the 2021 Tamil Nadu Assembly polls.

Following Karunanidhi’s death, DMK president M.K. Stalin further strengthened ties with Congress. However, the post-election developments of 2026 have now brought the alliance to a breaking point.
