Lower tax rates, interest-free agriculture loans up to Rs 1 lakh and steps to make India a USD 5 trillion economy by 2025 are among the key promises of the ruling BJP as it unveiled the manifesto for the general elections starting April 11.

Building 60,000 kilometres of national highways, connecting all villages with rural roads, operationalising 100 new airports, modernising 400 railway stations, and covering 50 cities are also part of the manifesto or 'Sankalp Patra (document of resolve)'.
