Union Minister M.K. Alagiri, who was upset with his father and DMK president M. Karunanidhi for backing his younger brother M.K. Stalin for the party leadership, called on him at his Gopalapuram residence on Tuesday.

Party sources refused to attach any significance to the meeting and sought to explain that the purpose of Mr. Alagiri’s visit was to call on his mother Dayalu Ammal, who is not doing well for sometime.

Mr. Karunanidhi, on January 6, after a meeting of the district secretaries, made it clear that Mr. Stalin was his choice to lead the party. On an earlier occasion, he had said Mr. Stalin was fulfilling his expectation, evoking a strong reaction from Mr. Alagiri who said the DMK was not a mutt (for an incumbent to anoint a successor).

DMK leaders said Mr. Karunanidhi was very angry with Mr. Alagiri for making such a sarcastic remark and that he had conveyed his displeasure to his close friends.

“Our leader’s argument is that Mr. Stalin is doing party work effectively and is touring the State extensively. Moreover, he did not expect Mr. Alagiri to react in the manner that he did,” said a DMK leader.

Party sources said Mr. Karunanidhi was firm in his stand that his choice would be Mr. Stalin and that the visit of his elder son would not make a difference. “Perhaps, it will help ease tension within the family, but is unlikely to impact on the party leadership’s stand,” the sources said.
