The INDIA bloc is facing mounting challenges as key allies struggle with internal divisions and political disagreements. The DMK's growing rift with Congress, a major rebellion within the Trinamool Congress and AAP's distancing from the alliance have raised concerns about opposition unity. The developments come ahead of a crucial INDIA bloc meeting in Delhi. Political observers say the alliance's biggest challenge remains the absence of a universally accepted leader and a cohesive strategy capable of keeping diverse regional partners together.
