Chennai: The DMK on Wednesday threatened disciplinary action against party members if they were found to be in touch with the now suspended party leader M.K. Alagiri.
In a statement issued here, general secretary K. Anbazhagan said Alagiri was causing confusion by organising meetings on the pretext of meeting his supporters.
Anbazhagan asked party activists to keep away from Alagiri.
On Jan 24, the DMK suspended Alagiri, 63, for opposing his brother M.K. Stalin, 61, after the latter was elected to the party's top post.
Both are sons of DMK leader and former chief minister M.K. Karunanidhi.
Recently, Alagiri met Prime Minister Manmohan Singh and BJP president Rajnath Singh, creating a flutter in political circles.
Alagiri also said he would discuss with his supporters and decide the formation of a new party.
Such actions ahead of the Lok Sabha election was creating confusion among DMK members, Anbazhagan said.
