There is a slight improvement in Dravida Munnetra Kazhagam (DMK) chief M Karunanidhi’s health, his son M K Stalin said in Chennai yesterday.
“His fever and infection has reduced,” DMK  working president Stalin said. 
Earlier politicians cutting across party lines visited Karunannidhi at his Gopalapuram home in Tamil Nadu’s capital Chennai.
Hundreds of supporters of the 94-year-old leader too gathered outside his home amid prayer and high emotion yesterday.
Doctors said the former chief minister is being treated for a urinary tract infection (UTI) and other geriatric complaints.
A team of doctors from Chennai’s Kauvery Hospital is attending to him round-the-clock.
Karunanidhi has been unwell for some time now with age-related health problems and has largely been confined to his home since late 2016. His tracheotomy tube was replaced last week.
His older son M K Azaghiri drove down from Madurai to Chennai on Thursday night, while his daughter M K Kanimozhi, who is a member of Parliament, flew in from Delhi in the morning. His other son and political heir M K Stalin too has been at the leader’s Gopalapuram home since early morning.
“Spoke to Stalin and Kanimozhi. Enquired about the health of Kalaignar and offered my assistance required. I pray for quick recovery and good health,” Prime Minister Narendra Modi tweeted.
Karunanidhi is called Kalaignar for his artistic script writing skills.
Among those who visited Karunanidhi’s home were Tamil Nadu’s Deputy Chief Minister O Panneerselvam and several state ministers from the DMK’s arch rival AIADMK (All India Anna Dravida Munnetra Kazhagam), in a gesture seen as rare in the personality-driven politics of the state.
They met Stalin and enquired about the medical support being given to the Dravidian leader.
“I was briefed that Karunanidhi is fine by Panneerselvam and I pray for his speedy recovery,” Chief Minister Edappadi K Palaniswami told reporters at Salem.
“Karunanidhi is fine. He will recover soon. We came here as part of political courtesy. Stalin visited Apollo Hospital when Amma (Jayalalithaa) was hospitalised,” said State Minister for Fisheries D Jayakumar, after visiting Gopalapuram on Thursday night.
The Tamil Nadu police have instructed officials to be alert and security has been tightened in the state capital as leaders and DMK cadres thronged Gopalapuram.
Police are cautions and ensuring that there are no law and order issues as thousands of supporters are known to visit the capital to pay their respects after the death of their favourite political leaders.
