Swamy in the letter to Modi said the BJP came to power under his inspiring leadership. "I cannot see why someone appointed by the UPA Government who is apparently working against Indian economic interests should be kept in this post when we have so many nationalist minded experts available in this country for the RBI Governorship."
He urged Modi "to terminate the appointment of Dr Raghuram Rajan in the national interest."
Swamy, who was earlier this month nominated to Rajya Sabha by the BJP government, said Rajan's concept of containing inflation by raising interest rates was "disastrous."
"When the Wholesale Price Index (WPI) started to decline due to induced recession in the small and medium industry, he shifted the target from WPI to the Consumer Price Index (CPI) which has not however declined because of retail prices. On the contrary it has risen.
"Had Dr Raghuram Rajan stuck to WPI interest rates would have been much lower today and given huge relief to small and medium industries. Instead they are squeezed further and consequent increasing unemployment," he wrote.
Rajan, Swamy said, was "acting more as a disrupter of the Indian economy than the person who wants the Indian economy to improve."
