Leader of the House in the Rajya Sabha and Finance Minister Arun Jaitley has said the best tribute to Dr B R Ambedkar is to further strengthen the democratic institutions. Initiating a discussion on Commitment to India's Constitution as part of the 125th Birth Anniversary celebrations of Dr Ambedkar in the House today, Mr Jaitley expressed grave concern over subversions in the ideological thinking in the country during the last 65 years.<br/><br/>He said the Constitution gave the concept of federalism to the country which is a reality in India today. Describing Dr Ambedkar as the best social reformer, Mr Jaitley said the architect of the Constitution showed the country the way to fight injustice through democratic institutions. Referring to reservations for weaker sections of the society Me Jaitley said an affirmative action is the need of the hour. He said the gravest challenge before the world has been posed by terrorism, which has to be severely dealt with.<br/><br/>Participating in the discussion, Leader of Opposition Ghulam Nabi Azad questioned the justification of observing 26th of November every year as Constitution Day. Mr Azad said the notification issued by the Social Welfare ministry about observing 26th November as Constitution Day is illegal and it should have been issued by the Home Ministry. Mr. Azad said, when you read Preamble of the Constitution, it conveys the objectives of Pandit Jawarhalal Nehru, but the BJP leaders don't mention him, adding that this is what is called intolerance. He said the government is trying to rewrite history by denigrating icons like Jawaharlal Nehru, Subhash Chandra Bose, Sardar Vallabhbhai Patel and Maulana Abul Kalam Azad
