Narendra Modi as prime minister, Modi reduced the amount of money spent by the central government on healthcare. The Modi government launched New Health Policy (NHP) in January 2015. The policy did not increase the government's spending on healthcare, instead emphasizing the role of private healthcare organisations. This represented a shift away from the policy of the previous Congress government, which had supported programmes to assist public health goals, including reducing child and maternal mortality rates. The National Health Mission, which included public health programmes targeted at these indices received nearly 20% less funds in 2015 than in the previous year. 15
