Tamil Nadu Chief Minister Vijay arrives in Delhi for his first high-profile meeting with Prime Minister Narendra Modi amid a fresh political flashpoint over Karnataka's proposed Mekedatu dam project. Ahead of the crucial talks, Vijay has written to the Centre urging it not to clear Karnataka's plans across the Kaveri river, calling it a violation of the 2018 Kaveri tribunal order. With Karnataka pushing ahead on the project and the Supreme Court dismissing Tamil Nadu's review plea, all eyes are now on whether Vijay's maiden Delhi visit can reset Centre-State ties and secure Tamil Nadu's demands on water, funds and approvals.
