An uproar erupted in Rajya Sabha after BJP chief JP Nadda said that Congress President Mallikarjun Kharge has lost his mental balance. Nadda had said, "You're...so indulged in your party's activities, that nation's cause becomes negligible for you, and after losing your 'mental balance', you utter unparliamentary words for PM Narendra Modi." However, Nadda later apologised and withdrew his remark.
