CHENNAI: An AIADMK delegation led by deputy chief minister O Panneerselvam on Thursday called on ailing DMK president M Karunanidhi at his residence here.

Panneerselvam and his cabinet colleague D Jayakumar said Karunanidhi was "doing well."

"Karunanidhi will return in good health soon," Jayakumar told reporters.

Jayakumar said it was political decency for the ruling party to visit Karunanidhi's residence, adding that a DMK delegation visited the Apollo hospitals here when former chief minister J Jayalalithaa was undergoing treatment in 2016.

The AIADMK delegation, which included ministers S P Velumani and P Thangamani, held discussions with Karunanidhi's son and working president M K Stalin.

Senior DMK leaders, including Duraimurugan and T R Baalu, were present during the meeting.

"There has been a slight decline in the health of DMK president M Karunanidhi due to age related ailments," a bulletin issued by Kauvery Hospital Executive Director Dr Aravindan Selvaraj earlier said.

The 94-year-old leader is currently being treated for fever due to urinary tract infection with intravenous antibiotics and fluids.
