Vidyasagar Rao was studying the situation in the state following divisions in the ruling AIADMK."The Governor is studying the situation," Naidu told media persons here.

Sasikala was chosen to replace O. Panneerselvam as the new Chief Minister, triggering a rebellion. Panneerselvam alleged on Tuesday night that he was forced to resign as the Chief Minister by V.K. Sasikala -- a long-time confidante of J. Jayalalithaa.Sasikala on Wednesday accused Panneerselvam, acting Tamil Nadu Chief Minister, of "betrayal".Official sources said in Mumbai that Vidyasagar Rao, the Maharashtra Governor who has additional charge of Tamil Nadu, has not finalised plans to go to Chennai.
