On meeting Raja, Karunanidhi said Raja would continue to be in the party and politics.
Karunanidhi said meeting Raja was like meeting his brother after a year.
Raja arrived here Friday evening to a tumultuous welcome by his supporters. From the airport he drove straight to the DMK headquarters here to meet Karunanidhi, who welcomed him with a garland.
"I will continue to be in DMK as a party cadre," Raja, the party's propaganda secretary, told reporters after meeting Karunanidhi.
To a query on Raja's political future, Karunanidhi said the former telecom minister would continue to be in the party and in politics.
Karunanidhi got upset when asked about the absence of pomp and show that marked his daughter Kanimozhi's return here from a jail in Delhi after she was granted bail in the same telecom case.
"You should not ask such questions," he shot back.
