Vice President M. Venkaiah Naidu will meet Dravida Munnetra Kazhagam (DMK) chief M. Karunanidhi at Kauvery hospital in Chennai today.
Karunanidhi was admitted to hospital on Saturday following a drop in his blood pressure.
The former Tamil Nadu Chief Minister is currently stable with ongoing medical support.
In a statement, Executive Director of Kauvery Hospital, Dr Aravindaran Selvaraj said that the 94-year-old leader is "being continuously monitored and treated by the panel of expert doctors in the Intensive Care Unit (ICU)."
Earlier on Saturday, Karunanidhi's daughter and Rajya Sabha Member of Parliament (MP) Kanimozhi informed that her father's health condition is now better.
Addressing the media outside Kauvery Hospital, Kanimozhi said, "Karunanidhi's health condition is now better and his blood pressure is also stable."
Meanwhile, Tamil Nadu Governor Banwarilal Purohit and Congress leader Ghulam Nabi Azad also visited the DMK chief at the hospital.
The DMK stalwart, who is suffering from fever due to urinary tract infection, was earlier undergoing treatment at his Gopalapuram residence in Chennai.
