Mr. Karunanidhi left by a private airline at 8.50 a.m. and was accompanied by senior leaders Duraimurugan and K. Ponmudy among others.
He is expected to meet Ms. Kanimozhi at Tihar jail on Tuesday and is likely to stay in Delhi for a day or two, DMK sources said.
The apex court had on Monday dismissed the bail pleas of DMK MP Kanimozhi and Kalaignar TV MD Sharad Kumar.
A special bench of justices G.S. Singhvi and B.S. Chauhan had asked the two accused to wait till framing of charges before approaching the special CBI court for regular bail.
The court said the CBI court can thereafter decide their bail pleas uninfluenced by the earlier bail proceedings.
This is Mr. Karunanidhi’s second visit to meet his jailed daughter after she was arrested about a month ago.
