Dravida Munnetra Kazhagam (DMK) chief M Karunanidhi's plan to appoint his younger son M K Stalin as his political heir has not been accepted by his elder son M K Alagiri as the Union Minister said the party was not a 'mutt' (religious body) to appoint a successor.
Speaking to reporters, Alagiri said: "The DMK is not a mutt."
He said his father had earlier said: "DMK is not a Sankara Mutt."
Karunanidhi on Thursday gave the clearest ever hint of his successor, naming party treasurer and his younger son Stalin as his heir-apparent.
"Till my last breath I will work for the upliftment of the society. To the question as to who will carry on this work after me, you should not forget Stalin, who is sitting here," Karunanidhi said at a function on Thursday.
The announcement by the DMK supremo at a function during which over 2,000 Pattali Makkal Katchi (PMK) members joined the DMK, evoked loud applause from party cadres.
The statement was the clearest backing for 59-year-old Stalin by the DMK chief since the party´s crushing defeat in the 2011 Tamil Nadu elections.
Muthuvel Karunanidhi Stalin, who holds the post of treasurer and youth wing secretary post in the party, is a former actor and is the third son of Karunanidhi, born to his second wife, Dayalu Ammal.
M. K. Muthu, M. K. Alagiri and M. K. Tamilarasu are other sons of Karunanidhi. His daughters are Selvi and Kanimozhi.
The DMK is a key ally of the Congress party at the Centre and the second largest constituent of the ruling United Progressive Alliance (UPA) coalition.
