With India striving to become a five-trillion-dollar economy by 2025, Vice President M. Venkaiah Naidu on Monday said the country has to go on an innovation overdrive to sustain the momentum.

Observing that the Indian growth story had taken the world by surprise and made the country an attractive investment destination, Naidu said: "For India's growth to be sustainable we have to go on an innovation overdrive. India just cannot afford to be obsolete any more."
