Chennai: Dravida Munnetra Kazhagam (DMK) leader and former Tamil Nadu chief minister M. Karunanidhi, 94, is stable and was responding to treatment, said chief minister Edappadi K. Palaniswami.

After a transient setback, the DMK patriarch’s vital signs showed improvement, the hospital said in a health bulletin on Sunday night.

On Monday, Palaniswami along with other ministers from the ruling All India Anna Dravida Munnetra Kazhagam (AIADMK) visited Kauvery Hospital where Karunanidhi is being treated.

After enquiring with DMK working president M.K. Stalin and Rajya Sabha MP Kanimozhi about their father’s health, Palaniswami said: “Kalaignar Karunanidhi’s condition is stable. I, along with the deputy chief minister, O. Panneerselvam, saw him being treated at the intensive care unit."

Talking to reporters at the Kauvery Hospital on Monday night, Stalin said that Karunanidhi’s “health condition remained stable, as mentioned in the yesterday’s health bulletin. He continues to be under observation."

Nationalist Congress Party (NCP) chief Sharad Pawar, along with former Union minister Praful Patel also visited Karunanidhi. Pawar tweeted: “Visited the ailing former chief minister of Tamil Nadu M. Karunanidhi in Chennai. Wished him a speedy recovery and good health."

Two ministers from Sri Lanka, Arumuga Thondaiman and Senthil Thondaiman also visited Kauvery Hospital. The ministers handed a letter from Sri Lanka’s president Sirisena to Stalin in which he had enquired about the health of Karunanidhi and wished him a speedy recovery.

On Sunday night, Kauvery Hospital had issued a medical bulletin on Karunanidhi’s health stating: “There was a transient setback in the clinical condition of DMK president M. Karunanidhi. With active medical support his vital signs are normalising. He continues to be closely monitored and treated by a panel of doctors."

DMK workers have continued to throng the hospital, raising slogans in praise of Karunanidhi and wishing him speedy recovery. Police had to resort to lathi charge on Sunday night as DMK cadres had refused to disperse. Subsequently, Stalin requested his party cadres to maintain calm and cooperate with the police.

Karunanidhi, the five-time chief minister, who fell ill in October 2016 due to a drug-induced allergy, underwent tracheostomy, a procedure that helped overcome his breathing difficulties, in December 2016. Later, the leader had undergone a procedure to change the tracheostomy tube.

The DMK chief, who was being treated for urinary tract infection since last week at his residence in Gopalapuram, Chennai, was hospitalised in the wee hours of Saturday, following a drop in his blood pressure levels.
