Clout: Rules Madurai and southern districts like his fiefdom. Karunanidhi has been very clear that his elder son would take care of party affairs in the south, but would not hold any post. This is only to ensure a smooth succession for Stalin.
Dayanidhi Maran, 39
Who: Karunanidhi's grand nephew, and Union Telecom Minister. Son of former Union Minister Murasoli Maran
Clout: Karunanidhi hoped Dayanidhi would lobby for DMK in Delhi. Has little by way of party base.
Kanimozhi, 39
Who: Karunanidhi's daughter by his 'second wife' Rajathi Ammal, the poet. Anointed by her father as his 'cultural heir'.
Clout: While the MK brothers, Stalin and Azhagiri, are keen to see Kanimozhi take on a more substantial role in Delhi, she has kept away from political limelight so far.
