The sibling war in the DMK is getting dirtier by day. A day after his suspension, former Union minister and elder son of DMK patriach M.K. Karunanidhi, M.K. Alagiri, has alleged large-scale corruption in the party, saying the party will lose in the Lok sabha elections. Meanwhile, his supporters conducted a meeting in Madurai to lend support to him.Alagiri, 62, told media persons on Saturday that he was suspended for questioning large-scale corruption in the party, adding, he will expose it on his birthday on January 30 in Madurai."They didn't investigate corruption. I questioned it. There is proof of corruption in the party. I have evidence and I will prove it soon in Madurai. Democracy is dead in this party. I will make an important announcement on 31st of this month," he said.Alagiri was suspended on Friday from the party on charges of going against the party's stand and airing divergent views on the issue of a possible alliance with actor-turned-politician Vijayakanth's DMDK. Alagiri was temporarily removed from all posts including the primary membership of DMK.Lashing out at party leader M.K. Stalin, whom Karunanidhi has chosen as his successor, and the DMK high command, Alagiri has asked why action wasn't taken against his brother for putting up posters hailing him."They are putting posters for him (Stalin) calling him the future of the party. Why is there no action against him?" Alagiri said.The suspended DMK leader now says he will not contest elections and the "party will lose" at the hustings.Alagiri loyalists are now gearing up to prove his strength in the Southern Districts. They have put up posters across the district for his birthday. Supporters also conducted a meeting in Madurai on Saturday to show their strength."I am the opposition leader in the corporation and district joint secretary. Without giving notice, they have suspended. I have participated in all party meetings and have also worked for the people in the corporation raising voices," says expelled Alagiri supporter Raja.On January 31, Alagiri may make an announcement regarding the next course of action. Many within the party and outside it are speculating if it could also be launching of a new party.The sibling rivalry is not new in the DMK. But this time around, it seems to have hit a new low. And this month end could be crucial for both Alagiri and DMK.
