Chennai: DMK president M Karunanidhi on Tuesday was declared to be 'extremely critical and unstable' by the hospital where he is battling for life.
The hospital, in a medical bulletin, said that the 94-year-old former Tamil Nadu chief minister's vitals have been deteriorating in the last few hours.
"There has been a decline in the medical condition of Karunanidhi. Maintaining his vital organ functions continues to remain a challenge considering his age-related ailments," said a statement from Kauvery Hospital earlier on Monday.
"He is on continuous monitoring and being treated with active medical support. His response to medical interventions over the next 24 hours will determine the prognosis," it said.
Hundreds of DMK workers flocked to the Kauvery hospital in Alwarpet in the heart of the city after the news of Karunanidhi's deteriorating health broke out Monday evening.
Outside the hospital, the DMK cadres kept shouting: "Get up and Come."
DMK general secretary K Anbalagan, Karunanidhi's family members and other leaders rushed to the hospital and had to wade through crowds who were still confident that the leader would fight the odds and come out victorious.
Police deployment was also stepped up to keep the situation under control.
The five-time CM was admitted to Kauvery Hospital on July 28 after a dip in blood pressure.
Late on Monday, union minister Nitin Gadkari visited the hospital and enquired about Karunanidhi's health.
In the last 10 days, a virtual Who's Who of Indian politics - right from president Ram Nath Kovind, vice-president M Venkaiah Naidu, Congress president Rahul Gandhi, former PM H D Deve Gowda and leaders from various parties including the BJP, Left and others - visited Karunanidhi at the hospital.
