A day ahead of a key meeting of the DMK, the eldest son of M Karunanidhi, who was expelled from the party four years ago, was seen at his father's gravesite. MK Alagiri told reporters that he had come to pay respects to his father. But he also added that he has the support of his father's loyalists - a statement seen as a warning to younger brother MK Stalin, who is yet to formally take charge of the party.
