Social activist Anna Hazare, the one time mentor of Delhi Chief Minister Arvind Kejriwal, has said that latter should step down from his post as he is facing serious graft charges. "Arvind Kejriwal should step down as CM pending a probe. He should start a probe into his dealings," Anna Hazare said while speaking to news channel CNN-News18. "It is sad to see that founders of anti-corruption movement are facing corruption charges," Hazare further told the news channel. Hazare’s statement comes at a time when Arvind Kejriwal is embroiled in a massive controversy following graft allegations made by sacked Delhi minister Kapil Mishra.
