The incident has stirred strong speculations that whether the state unit of the Central ruling party has been covering more people for its campaign by using the baits of money and food.
The hospital said that owing to her current clinical condition, she has been moved to the Intensive Care Unit (ICU) and she has been getting continuously monitored by a team of doctors.
She wrote to her counsel in October and asked the team to keep the fine amount ready and she had expressed confidence that she would be released early.
The possible rise of Alagiri against Stalin and against DMK would cause a political storm in Stalin's bid to become a perfect successor for Karunanidhi beyond being his heir.
Upon having the confirmation that he has demised, the police had booked Natarajan, who shot and injured the two men, under section 300 (murder) of the Indian Penal Code.
It has been expected that Alagiri could flip Stalin's stronghold to his side after launching the party and if he allies with the BJP - ADMK alliance, the DMK would further face more challenges in building its rule.
