Union Minister Mansukh Mandaviya on Monday said the government's infrastructure investment budget should be Rs 15 lakh crore per annum, against Rs 11.5 lakh crore at present, for the next 25 years to achieve 'Viksit Bharat @2047' and social security for all. This assumes significance in view of India's 100 years of independence in 2047 and the government's goal of 'Viksit Bharat@2047'. Addressing the inaugural of ISSA-ESIC International Seminar 'Formalization & Social Security Coverage for Workers in the Informal Sector Challenges & Innovation', Mandaviya stated that the infrastructure investment budget was Rs 1.2 lakh crore in 2012 and this budget was Rs 2.4 lakh crore in 2014 under the Narendra Modi-led government.
