Rajya Sabha Chairman M Venkaiah Naidu continued with his “Venkaiah-isms” on Tuesday. When a member of a regional party in the House persisted with raising an issue during the zero hour in the morning, Naidu retorted: “Don’t think you will become the hero of this zero hour.” On another occasion, when the Congress party protested the insult to former prime minister Manmohan Singh by Prime Minister Narendra Modi during the Gujarat election campaign, Naidu appealed to them to maintain calm. “My operation (of the House) depends on your cooperation,” he said.
