New Delhi:  Finance Minister Arun Jaitley on Wednesday said the UPA's "ease of doing corruption" has been replaced by NDA's "ease of doing business", apparently hitting back at Congress vice president Rahul Gandhi's jibe at him after a World Bank business index showed that India has improved its global ranking by 30 notches.

In his tweets earlier in the day, Gandhi took potshots at the finance minister saying people knew the "reality" of the 'ease of doing business' but the improvement in survey rankings was a good thought to keep "Dr Jaitley" happy.

Jaitley took to twitter to retort: "The difference between the UPA and NDA - The ease of doing corruption has been replaced by the ease of doing business'". The World Bank on Tuesday released a report showing that India has improved its rank by 30 notches to 100th position in the ease of doing business index.

"Everyone knows the reality of 'ease of doing business', but it is a good thought to keep oneself happy 'Dr Jaitley'," Gandhi had tweeted a couplet in Hindi.
