Accusing the BJP of using nasty tactics to win the upcoming Gujarat Assembly elections, Shiv Sena chief Uddhav Thackeray slammed the party for releasing Patidar leader Hardik Patel's sex CD. "If you have guts, show the CD of your 22-year-rule," Thackeray said. PM Modi is planning 50 public meetings as BJP's sole aim is to win the elections, he added.
