Prime Minister Narendra Modi had yesterday warned of "tough decisions" over the next couple of years to improve the country's financial health, which he said may not go down well with some sections, and attacked the way the previous UPA government had handled the economy.
"Taking tough decisions and strong measures in the coming one or two years are needed to bring financial discipline which will restore and boost the country's self-confidence", he had said addressing BJP workers in Mumbai.
India's economic growth remained below the 5 per cent mark at 4.7 per cent in 2013-14. It remained subdued at 4.6 per cent in the fourth quarter of 2013-14 and during the entire fiscal, mainly due to a decline in manufacturing and mining output.
The country's economy, or gross domestic product (GDP), had expanded at 4.5 per cent in 2012-13, the slowest pace in the previous decade.
