Congress President Mallikarjun Kharge on Thursday said he will resign if 'land grab' allegations levelled against him by BJP MP Anurag Thakur are proved. "All media outlets carried the story, and social media spread it, damaging my image and reputation," Kharge said. "Thakur cannot prove his allegations, he has no right to be in the Parliament...[he] should resign," Kharge added.
