"Challenge Accepted": Niti Aayog's Rajiv Kumar hits back at P Chidambaram, even as Arun Jaitley defends UPA GDP revision

Finance Minister Arun Jaitley on Thursday defended the revision in India's GDP growth rate during the previous UPA era, saying the Central Statistics Office (CSO), which came out with the revised numbers, was a credible organisation and maintains arm's length distance from the finance ministry.

A day after Chief Statistician Pravin Srivastava announced the revised numbers based on back series data alongside Niti Aayog vice-chairman Rajiv Kumar, Jaitley said, "I don't think any service is being rendered by those who discredit the highly credible organisation, CSO."

Former Finance Minister P Chidambaram had Wednesday called the revision a "bad joke."

"Niti Aayog's revised GDP numbers are a joke. They are a bad joke," he had tweeted. "Actually they are worse than a bad joke. The numbers are the result of a hatchet job."

Jaitley said when the CSO had revised upward the growth rate of 2012-13 and 2013-14, the then government had welcomed the decision.

The same yardstick has been applied by the CSO while revising the growth downwards, he said.

Just months before the general elections, the country's economic growth rate during the previous Congress-led UPA regime was lowered Wednesday, shaving off over 1 percentage point from the only year when India posted double-digit GDP growth post liberalisation and from each of the three years with 9-plus per cent expansion.

Recalibrating data of past years using 2011-12 as the base year instead of 2004-05, the CSO estimated that India's GDP grew by 8.5 per cent in the financial year 2010-11 (April 2010 to March 2011) and not at 10.3 per cent as previously estimated.

Similarly, 9.3 per cent growth rate each in 2005-06 and 2006-07 was lowered to 7.9 per cent and 8.1 per cent, respectively, while 7.7 per cent rate was now estimated for 2007-08 instead of 9.8 per cent.

Chidambaram had called the revision a "hatchet job" by Niti Aayog.

"Now that Niti Aayog has done the hatchet job, it is time to wind up the utterly worthless body," he had tweeted. "The earlier numbers were calculated by the National Statistical Commission. Has the commission been disbanded?"

"Former Chief Statistician Pranab Sen is absolutely correct. Niti Aayog has nothing to do with tabulation of data," he had said. "I wonder if Niti Aayog Vice Chairman Rajiv Kumar will agree to a debate the data than telling journalists that their questions are "undeserving of an answer", he said.
