The decks are clear for Mk Stalin's elevation as the DMK president. He will officially become the boss of the party today. DMK loyalists say Stalin exercises full control over the party. His half brother Azhagiri on the other hand has dropped yet another hint at a rebellion against Stalin and the party. Establishing himself as a direct challenger to Stalin, Azhagiri said that he will file a nomination if there is a by-election held. Azhagiri is set to hold a rally in Tamil Nadu on September 5. Earlier sources told NewsX that Azhagiri will disclose his plans after this rally.
