Economist Harsh Gupta Madhusudan joins NDTV to discuss the controversy surrounding India's latest GDP numbers and the claim that actual growth was only 2.6% rather than the reported 7.8%. He explains why GDP figures from different base-year series cannot be directly compared, how India's recent rebasing has incorporated newer data sources such as GST, UPI and e-commerce, and why regular revisions are standard economic practice worldwide. He also discusses India's sovereign credit ratings and what the latest data means for the country's growth story and investor confidence.
