NEW DELHI: Prime Minister Narendra Modi on Saturday slammed the opposition for raising doubts and questioning the improvement in India's ranking in World Bank 'ease of doing business ' index. Taking a swipe at the Congress, he said those who worked with the World Bank are today raising doubts about India's ranking.

"Today some people are expressing doubts about the improvement in India 's rankings. Many of these people are those who have worked with the World Bank. I am the kind of PM who hasn't even seen the World Bank, when earlier people in my position had run the World Bank,'' Mr. Modi said  at the presentation of India’s Business Reforms at Pravasi Bharatiya Divas.

In an oblique attack at the previous UPA Government at the Centre, Mr  Modi said, ''I want to tell them that had they done the kind of work we have, this achievement would have come during their tenure itself. They don’t want to work, but are quick to question those who do.''

The Prime Minister said the reforms undertaken by the NDA Government are far more extensive than those carried out by the previous government. 

''The Opposition didn't do 'big bang' reforms. Now they're without answers,'' Mr Modi said at the event. World Bank CEO Kristalina Georgieva and Commerce Minister Suresh Prabhu were present.

World Bank chief Kristalina Georgieva had described India's jump of 30 places in World Bank's ease of doing business ranking as "very rare". "In reforms what pays off is persistence, what we are seeing is extraordinary achievement by India," Ms Georgieva said.
