Even as Tamil Nadu Chief Minister C. Joseph Vijay fired off a strongly-worded letter to Prime Minister Narendra Modi opposing Karnataka’s proposed Bhoomi Puja for the Mekedatu dam project, the political contradiction at the heart of the controversy is becoming impossible to ignore.
The Karnataka government pushing ahead with the Mekedatu project is led by the Congress party under Chief Minister Siddaramaiah and Deputy Chief Minister D.K. Shivakumar. At the same time, Vijay’s TVK government in Tamil Nadu survives with the support and alliance of the very same Congress party.
In his letter dated 26 May 2026, Vijay accused Karnataka of acting in “clear violation” of the Supreme Court judgment and the Cauvery Water Disputes Tribunal award, and urged Prime Minister Narendra Modi to intervene and stop the project. But the move seems to be hypocritical – that Vijay chose to appeal to the BJP-led central government instead of first forcing accountability from his own alliance partner.

Now, if the TVK-Congress alliance was truly based on coordination and shared governance principles, Vijay should ideally have publicly confronted Congress leadership directly, including Rahul Gandhi and the Congress high command, over Karnataka’s aggressive push for the reservoir project. Instead, the Tamil Nadu Chief Minister has effectively written to Narendra Modi asking the Centre to restrain a Congress government that his own administration politically depends on.
The contradiction becomes even starker because Karnataka Congress leaders have repeatedly backed the Mekedatu project as a priority initiative. Reports earlier this year noted that Karnataka was actively moving toward revised DPR submissions and pushing administrative clearances for the project despite Tamil Nadu’s objections.
This episode exposes the fragile and transactional nature of the TVK-Congress arrangement. While TVK projects itself in Tamil Nadu as a defender of Cauvery rights and Tamil farmers, its alliance partner in Karnataka continues to champion a project Tamil Nadu has consistently described as a direct threat to its water interests.
The controversy has already begun raising uncomfortable questions for the ruling alliance: if Congress is genuinely an ally to TVK in Tamil Nadu, why is a Congress government in Karnataka escalating the Mekedatu issue? And if Vijay truly has political leverage within the alliance, why is he petitioning Narendra Modi instead of compelling Congress to rein in its own Karnataka leadership?
