New Delhi:10 Dec 2020 To mark the symbolic launch of the new parliament building on the Central Vista today, Prime Minister Narendra Modi will attend a groundbreaking ceremony at the heart of Delhi near India Gate. The actual construction, however, cannot begin immediately, with a petition challenging the project pending in Supreme Court. The new parliament building is the key piece of the ₹ 20,000-crore Central Vista project, which aims to build and refurbish the government buildings on part of the 13.4-km Rajpath that stretches from the presidential palace Rashtrapati Bhavan to the iconic war memorial India Gate.
