AAP supremo Arvind Kejriwal Tuesday cautioned the people of Tamil Nadu to be “wary” of NDA, saying if they voted that alliance to office, it will undo DMK chief M K Stalin’s good work. On dynasty rule and corruption allegations against DMK, Kejriwal said that BJP should first look at its own party. “What is Amit Shah’s son doing? What is Rajnath Singh’s son doing? BJP is the most corrupt party today. PM Modi is giving away everything to his friends,” Kejriwal added.
