Apart for OPS and some rebel MLAs, some MP's have also taken part in the protest.
On Monday, the State government released the treatment summary of Jayalalithaa and said she had neither suffered trauma nor had she been given any wrong medication.
Jayalalithaa died on December 5 a year ago after being in the Apollo Hospitals here for around 75 days. Back then, the party claimed that she is suffering from fever and dehydration but the medical reports said she was admitted in an unconscious state. After her death, O Panneerselvam was named as the CM of Tamil Nadu but after his resignation from the same post, he remained the caretaker Chief Minister of Tamil Nadu until the appointment of the new Tamil CM Edappadi K Palaniswami.
The government on 7 March, 2017 rejected Panneerselvam's claims, saying the latter is spreading false information among the people regarding Jayalalithaa's health condition.
The opposition Dravida Munnetra Kazhagam (DMK) had also approached the Madras high court seeking a comprehensive probe into the death of Jayalalithaa. "The first spark of doubt comes there, especially when she had a hospital-like set-up at her own residence", Dr. Maitreyan was quoted by the Finacial Express.
Panneerselvam supporters across the state will also be observing fast in the various district headquarters across Tamil Nadu.
