Shiv Sena Uddhav Thackeray faction member Arvind Sawant on Monday condemned the "ban" on the entry of party MP Dhairyasheel Mane into Karnataka's Belagavi district and called it an attack on the Constitution. Raising the issue during Zero Hour in the Lok Sabha, the South Mumbai MP also called for Union Home Minister Amit Shah's intervention in the matter and demanded protection to Maharashtra Ekikaran Samiti's leaders following Karnataka Police's action against some of them during a protest in Belagavi.
