Shanmugam said Palaniswami was not elected CM by the MLAs after the 2016 elections and, under his leadership, the party lost power in 2021, leaving him as the Leader of the Opposition.
Viswanathan and Velumani said that AIADMK MLAs were forced to adopt an anti-DMK position after the 2026 Assembly election because of EPS' "wrong decision" to form a government with the DMK.
Under the new appointments, C Vijayabaskar has been named Pudukkottai district organisational secretary, while M R Vijayabhaskar will serve as Karur district organisational secretary.
Recalling the earlier practice, Palaniswami said both AIADMK and DMK governments had consulted political parties and farmers before approaching the Supreme Court to secure Cauvery water.
