Set up in 2017, the commission has run into episodes of twists and turns and has inquired about hundreds of people who are connected to the hospitalization and the demise of Jayalalithaa.
The summon to VK Sasikala has come days after the probing team had interrogated former ADMK MLA Aarukutty for nearly ten hours in connection with the case.
Paneerselvam has appeared before the commission for the second straight day and during the inquiry, he had twisted his own tale by opening up a fresh confession.
The commission was set up based on the demand from Panneerselvam and now he has made an attempt to estrange himself from finding the fact of the final days of Jayalalithaa.
It must be noted that VK Sasikala is not active in politics after getting released from the Karnataka prison last year. She neither campaigned nor endorsed any party in the local body polls.
Karnataka's Anti-Corruption Bureau has filed a charge sheet against VK Sasikala and Illavarasi as it has begun another round of investigation into the special treatment awarded to the duo.
On Tuesday, the DMK ruling Tamil Nadu government has announced that the clinics will be closed and the ADMK had called the decision of closing as a political vendetta.
