Tamil Nadu Chief Minister M.K. Stalin has formally urged Prime Minister Narendra Modi to intervene diplomatically with Sri Lanka to protect the rights and aspirations of Sri Lankan Tamils, amidst the island nation's ongoing constitutional reform process. In a letter dated January 11, 2026, Stalin highlighted his profound concern that the proposed new Sri Lankan constitution threatens to further marginalize the Tamil community by reinforcing a unitary 'Ekkiyarajya' state model, which he argues ignores their legitimate demands for political autonomy. Stalin detailed how post-independence Sri Lankan constitutions (1947, 1972, 1978) have been rooted in a unitary structure, leading to decades of systematic discrimination, violence, and the denial of basic rights for Tamils. He pointed out that even after the 2009 civil war, demographic changes, land grabs, and the erosion of Tamil identity in their traditional homelands have continued. The Chief Minister stressed that India has a moral and strategic imperative to act, citing its historical commitment to peace and justice in Sri Lanka, including the 1987 Indo-Sri Lanka Accord. He specifically called upon India to press for the inclusion of federal arrangements that devolve power to the provinces, protect ethnic minority rights, and uphold principles of pluralism and equality. Stalin also invoked the enduring relevance of the 1985 Thimpu Principles, articulated by Tamil representatives, which advocate for the recognition of Sri Lankan Tamils as a distinct nation, acknowledgment of the Northern and Eastern Provinces as their traditional homeland, the right to self-determination, and a federal system of governance ensuring equality. This intervention underscores the deep historical, cultural, and emotional ties between Tamil Nadu and the Sri Lankan Tamil community.
