Prime Minister Narendra Modi's dig at Congress leader Renuka Chowdhury left parliamentarians bursting into laughter in the middle of his speech in the Rajya Sabha. Ms Chowdhury, who had been laughing at PM Modi, was stunned into silence. The Congress leader's loud chuckling had infuriated Rajya Sabha chairman Venkaiah Naidu, who stopped PM Modi mid-sentence to admonish the 63-year-old. "What happened to you," Mr Naidu asked Ms Chowdhury sternly, declaring that "unruly behavior and loose talk" would not be allowed. (Video Courtesy: Rajya Sabha TV)
