Telangana Governor Tamilisai Soundararajan on Thursday said the state government has 'undervalued' the importance of the Republic Day and has not held any official function to mark the occasion. Soundararajan, who is the Lt Governor of Puducherry, voiced concern over violations in observing conventions by the BRS regime in Telangana, which went against the vision of Dr B R Ambedkar, the architect of the Constitution.
