"Jayalalithaa was heading a corruption-free government in her initial days but friendship (with Sasikala) got her involved in corrupt practices, the result of which was this conviction," party's state unit president Tamilisai Soundararajan told reporters at the airport here.
The verdict would now lead to cleansing of Tamil Nadu politics and also entry of corruption-free persons to govern the state, she said.
However, BJP was not interested in "entering through the back door" and people had realised that the party wanted a corruption-free government to be installed in Tamil Nadu, she said.
"This (not inviting Sasikala) could be the first step towards installing a corruption-free and stable government in Tamil Nadu. The MLAs should not bow to coercion and compulsion and should now concentrate on the welfare of people and the state," she said.
"Why should they (MLAs) stay in a resort when they have their own houses in their constituency and Chennai can be reached in a shortest possible time as it is not America or Russia?" she quipped.
Tamilisai said she was here to pay homage to those killed on this day in the 1998 serial bomb blasts.
