The Supreme Court is expected to rule tomorrow on whether VK Sasikala, who wants to be head Tamil Nadu, conspired in the early 90s with J Jayalalithaa to illicitly acquire a shared fortune then worth over 60 crores. Ms Jayalalithaa died in December while she was still Chief Minister; O Panneerselvam, a loyalist who had filled in twice for her when she had to take leaves of absence from office because of charges of venality, once again was promoted. In the weeks that followed, the state's ruling party, the AIADMK, appeared to be running smoothly. Gears began grinding a week ago, when Mr Panneerselvam, or OPS as he is known, said he would not allow Ms Sasikala to replace him as Chief Minister, as decided by the party.
