Tamil Nadu's ruling AIADMK is locked in an ugly war within as acting Chief Minister O Panneerselvam has vowed to stay put in office while party General Secretary VK Sasikala Natarajan accused him of trying to split the party with the opposition DMK's backing.

A night after Panneerselvam revolted against Sasikala, who had been elected the AIADMK legislature wing leader, the long-time confidante of former Chief Minister J Jayalalithaa accused Panneerselvam of "betrayal" after he refused to back her plans to head the government.

On his part, Panneerselvam announced that a Supreme Court judge will head a Commission of Inquiry to probe the December 5 demise of Jayalalithaa. He said there were many questions over the death.

Both camps claim majority support among the AIADMK's 134 legislators in Tamil Nadu, with reports saying most of them have been bussed away to a hotel near the Chennai airport.

Tamil Nadu Governor Ch. Vidyasagar Rao is expected to play a key role in resolving the crisis -- or recommend President's Rule in the state.

Here are the LIVE updates:

According to sources, Sasikala is expected to meet the governor who will be in Chennai on Thursday.

OPS writes to banks says not allow transactions without his permission/assertion as he is the treasurer of AIADMK. Earlier Sasikala has removed from the post.

Governor Vidyasagar Rao finally broke his silence. He said, "I am also in charge as a Governor of Tamil Nadu. A lot of political development is taking place in the state. The moment you put TV sets in your house Tamil Nadu news is coming and various debates are going on. Now and then they say where is the Governor of Tamil Nadu. And Im happy here to be with you amidst nobel laureates."

PANNEERSELVAM REVOLTS

Immediately after being sacked from the post of AIADMK treasurer by party General Secretary VK Sasikala, Chief Minister O Panneerselvam said that no one had the right to do so and dismissed claims that DMK influenced his move.

He said his next course of action would "reflect" the "aspirations" of AIADMK cadres and people of Tamil Nadu.

WATCH | No one in Tamil Nadu has the right to take away my treasurer post: O Panneerselvam on his expulsion

"No one has the right to remove me from the post of treasurer which was given to me by Amma 10 years ago," he told reporters.

Asked if the AIADMK chief had charged him with association with DMK as she could not find any other allegation, he quoted a Tamil proverb, the meaning of which is "I have nothing and no one to fear as I have done no wrong."

Panneerselvam also said "I am a grassroot-level ordinary party worker." Asked if he would launch a new party and if he would call on Governor Ch Vidyasagar Rao, he said "please wait and see."

WHAT LIES AHEAD FOR TAMIL NADU: With the tumultuous wave of change in the last couple of hours AIADMK is most likely heading for a split. O Panneerselvam saying that he was under pressure to resign, gives the Tamil Nadu governor enough to reconsider the letter by using his discretion. One will need to wait and see how many MLAs are with O Paneerselvam and how many support with VK Sasikala. Sasikala team is getting the jitters as O Paneerselvam spoke openly about how he was the shown candidate for the chief minister post and how he is ready to fight this battle alone, with this he will most likely be expelled from the party for anti-party activities.
