The arrest of Tamil Nadu Minister R. K. Nagar has elicited mixed reactions from opposition leaders. Here's a breakdown of the major opinions:

• DMK leader M.K. Stalin and Congress leader Rahul Gandhi have both criticized the AIADMK government for what they perceive to be political vendetta. They allege that R.K. Nagar was targeted for his loyalty to VK Sasikala, who is currently in jail.
• BJP leader H. Raja has stated that the arrest was a result of internal party divisions within the AIADMK, and that the BJP was not involved.
• PMK leader S. Ramadoss has maintained that while the arrest may be seen as vendetta, it is ultimately a positive development for Tamil Nadu's democracy. He believes that corruption must be rooted out of politics, even if it means arresting politicians from your own party.
• CPI leader D. Raja has criticized the timing of the arrest, which comes just ahead of the crucial RK Nagar bypoll. He argues that it suggests a political motive rather than a genuine commitment to fighting corruption.

Overall, it is difficult to determine whether the arrest was an act of vendetta or a lawful action. However, the mixed opinions from opposition leaders indicate that there is still much debate to be had on the issue.
