"I will work till my death for the upliftment of the Dalit community. After my lifetime it will be Stalin whom you should not forget," Karunanidhi said at a function in which over 2,000 PMK members joined the DMK.
Karunanidhi said he is the father-in-law of a Dalit woman as his elder son and union minister M.K. Alagiri's wife Gandhi belongs to that community.
The DMK chief said there is no measure of his happiness when Gandhi calls his wife 'aththai' (aunt).
