The strain has exposed the bloc’s core weakness: its national claim rests on parties whose strongest compulsions remain regional. The alliance, formed in 2023 to consolidate anti-BJP votes for the 2024 Lok Sabha election, had gained political relevance by denying the ruling party a single-party majority. Yet its ability to function as a durable national platform is now being tested by state-level rivalries, leadership disputes and conflicting electoral calculations.
The most immediate setback has come from Tamil Nadu, where the Dravida Munnetra Kazhagam has decided not to attend the June 8 INDIA bloc meeting in Delhi after its rupture with the Congress following the state election. The party has also obtained separate seating in the Lok Sabha, a symbolic parliamentary shift that underlines the breakdown of floor coordination with the Congress. DMK leaders have framed the decision as a response to what they see as Congress conduct during the Tamil Nadu campaign, while stopping short in some statements of abandoning wider opposition coordination entirely.
For the Congress, the Tamil Nadu rupture is damaging because the DMK was among the bloc’s most dependable regional anchors in the 2024 national contest. The partnership had helped the alliance hold ground in a state where the BJP has sought to expand. Its erosion raises questions over whether Congress can manage alliances in states where it is either a junior partner or a direct competitor for opposition space.
West Bengal presents a different challenge. The Trinamool Congress, another key opposition force, is facing public dissent around its leadership structure after weeks of internal turbulence. Disagreements involving party founder Mamata Banerjee, Abhishek Banerjee and a group of MLAs have moved from private party channels into public view. The party’s decision to dissolve organisational committees and frontal bodies has been interpreted as an attempt to reset internal authority, though it has also highlighted the depth of factional strain.
The Trinamool’s position in the INDIA bloc has long been complicated. It shares the anti-BJP space with Congress and the Left in Parliament, but fights them fiercely in West Bengal. Mamata Banerjee has backed opposition coordination at the national level, including a Delhi meeting, yet her party’s immediate priority is to defend its state base and manage internal unrest. That limits the scope for a unified national opposition line.
The Aam Aadmi Party’s position adds another layer of uncertainty. AAP had already made clear after the 2024 Lok Sabha election that its arrangement with Congress was limited and would not automatically extend to state polls. The party has since focused on rebuilding strength in Punjab, where civic poll results showed it retaining significant urban traction despite pressure from the BJP and Congress. Its leaders have also criticised the BJP over defections and political manoeuvring, but that has not translated into a renewed commitment to Congress-led seat-sharing.
AAP’s decision to keep distance from central alliance arrangements reflects its own political arithmetic. It competes directly with Congress in Delhi, Punjab and parts of Gujarat, making a permanent pact difficult. The party’s leadership also views its anti-corruption and governance pitch as distinct from Congress’s broader coalition approach.
The BJP has benefited politically from these contradictions, portraying the opposition bloc as a temporary election arrangement rather than a coherent governing alternative. Its national position has also been strengthened by defections and its expanding footprint in several states, giving it room to exploit divisions among rivals.
