Assam Congress president Gaurav Gogoi challenged CM Himanta Biswa Sarma to deny Congress's claims regarding his wife's multiple passports and properties abroad by swearing on Bhagavad Gita. "I can say under an oath...that I don't have any property in London as alleged by Sarma," Gogoi said. "I challenge him...to do the same under an oath of Bhagavad Gita," he added.
