O. Panneerselvam reads outs a statement at his residence — a passionate plea to AIADMK MLAs. It was Jayalalithaa’s wish to wipe out dynastic rule in Tamil Nadu, he says.

He expresses happiness about Mylapore MLA R. Nataraj’s decision to side with him after his request. AIADMK MLAs should vote according to their conscience, he adds.

“If you are Amma’s true loyalists, you should vote against the (Palaniswamy) government when it seeks trust vote in the Assembly tomorrow,” Mr. Panneerselvam says.

OPS camp ‘removes’ Sasikala

In a tit for tat, the O. Panneerselvam camp “removed” AIADMK general secretary V.K. Sasikala and her two relatives from the party for “going against its principles and ideals”.

In a statement, E. Madusudanan, who was earlier removed as Presidium Chairman by Ms. Sasikala, said she had “violated” her promise to the late Jayalalithaa that she will not enter politics and that she had no inclination to be a part of the party or the government. He asked the cadres not to have any association with Ms. Sasikala.

The development came a day after Mr. Palaniswami was sworn in as Chief Minister.

“V.K. Sasikala is being removed from the party’s primary membership for going against the party principles and ideals, and having violated her promise to Amma [Jayalalithaa], besides facing criminal cases. She has brought disrepute to the party,” he said in a statement.

Mr. Madusudanan, who joined the Panneerselvam camp last week, was replaced by Mr. Sengottaiyan as the Presidium Chairman. He was also removed from the party’s primary membership but he insisted that Ms. Sasikala had no authority to do so.

Ms. Sasikala, serving a jail term in Bengaluru in connection with the Rs. 66 crore disproportionate assets case, had also removed former Chief Minister O. Panneerselvam from the party’s primary membership in the wake of his revolt against her.

Mr. Madusudanan also announced the “expulsion” of AIADMK deputy general secretary T.T.V. Dinakaran and S. Venkatesh, both relatives of Sasikala, from the party.

He said Ms. Jayalalithaa had (in 2011) expelled them from the party for “betraying” her. “Their re-induction, done without any authority, is being cancelled,” he said.

The two were allowed to join the AIADMK on Wednesday by Ms. Sasikala, after six years of expulsion by Jayalalithaa.

Ms. Sasikala had announced that they were being allowed to join after they expressed regret for their acts in person and through letter and requested that they be allowed to join the party again.

Mr. Panneerselvam had revolted against Ms. Sasikala on February 7, alleging he was forced to step down to make way for her elevation as chief minister.

She was elected the AIADMK Legislature Party leader on February 5 to enable her become chief minister. But the Governor, Ch. Vidyasagar Rao, had apparently chosen to await the outcome of the Supreme Court verdict in the disproportionate assets case.
