On May 12, 2026, TTV Dhinakaran, the general secretary of the Amma Makkal Munnettra Kazhagam (AMMK), expelled S. Kamaraj, the party's only Member of the Legislative Assembly (MLA) representing Mannargudi constituency, for what he termed 'anti-party activities.' This decision came after Kamaraj expressed support for the Tamilaga Vettri Kazhagam (TVK) government during an Assembly session, which Dhinakaran viewed as a betrayal. Dhinakaran previously alleged that Kamaraj had been involved in a forged letter of support to the Governor of Tamil Nadu, Rajendra Vishwanath Arlekar, purportedly submitted by TVK founder C. Joseph Vijay. The controversy escalated when Kamaraj was initially untraceable, raising questions about his loyalty to the AMMK. However, he was later located and appeared alongside Dhinakaran at a media briefing on May 9, 2026, amidst the unfolding drama.
