The decision came four days after leaders told Mr Dhinakaran - accused of trying to bribe EC officials - to keep off the party.
A day after the two factions of the All Anna India Dravida Munnetra Kazhagam (AIADMK), one led by O. Pannerselvam and the other by V.K. Sasikala chose to come together, the former state chief minister on Tuesday said that he has sent a petition to the Election Commission to declare Sasikala's appointment as general secretary as illegal.
A committee will be formed soon to run the day-to-day affairs of the party, he said. Sasikala was a close aide of Jayalalithaa, whose death in December forced a by-election in the R.K. Nagar assembly constituency. "But if they are bribing the Election Commission then it proves that they don't have the majority", DMK senior leader TKS Elangovan told ANI here.
Panneerselvam, expelled by Sasikala following his revolt against her in February this year, also remained firm on his faction's demand for a probe into late J Jayalalithaa's death. Dinakaran, a former MP, was the candidate of AIADMK (Amma) faction for the seat.
Jayakumar, flanked by several ministers, said they were prepared to hold talks with Panneerselvam. With today's announcement, there are three factions in Tamil Nadu headed by Palaniswami, Panneerselvam and Dhinakaran, who is filling in for Sasikala, jailed in connection with the DA case in which Jayalalithaa was the main accused.
Both factions of Tamil Nadu's ruling AIADMK have shown inclinations of a rapprochement, but neither camp has managed to find a middle ground.
"There was a consensus to de-link the government and the party from T.T.V. Dinakaran and the family he belongs to".
"This is the decision of 1.5 crore party cadres and we are united".
Panneerselvam too has vowed to free the state from the clutches of Sasikala and her family.
He adds: "The core issue with both of us remains the symbol of Two Leaves".
The fissure in the Sasikala camp widened when her loyalist and Perambur MLA P Vetrivel, after meeting Dinakaran, questioned the authority of ministers to hold a meeting in the absence of party deputy general secretary TTV Dinakaran.
But the Election Commission froze the symbol and asked the two factions to choose other symbols.
Dinakaran, who is a nephew of VK Sasikala has denied the allegation against him, calling it false. Dinakaran has said: "I have never heard of this man". The two different meetings are held between both camps at residences of ministers Thangamani and Udumalai Radhakrishnan. "I will face it legally", he said.
The police action, which indicates that an arrest could be in the making, comes in wake of inputs that Dhinakaran, a non-resident Indian, might try to flee the country, police said.When contacted, joint commissioner (crime) Praveer Ranjan confirmed the move but refused to share details.
"The middleman (Sukesh Chandrasekar) was caught through central intelligence".
