Karunanidhi made the announcement in his concluding remarks at the meeting of the partys key decision-making body,the general council,to rapturous applause from members,reflecting the anti-Congress mood in the party ranks.
Party sources claimed that Karunanidhi hinted that the DMK may not forge an alliance with the BJP also but the leader himself made a non-committal reply on this.
Sources said he had indicated that the BJPs present leadership was different from A B Vajpayee who had headed the NDA government of which the DMK was a constituent.
A committee has been formed and it will discuss and decide on the alliance, was his response to reporters queries when asked if he still kept the BJP as an option.
DMK sources present at the meeting said Karunanidhi ruled out a tie-up with the Congress,referring to the 2G spectrum scam which has turned out to be the gravest allegation faced by the DMK in many years.
Karunanidhis daughter Kanimozhi and junior colleague and former telecom minister A Raja are accused in the scam.
