RSS ideologue and independent director on RBI board S Gurumurthy Monday described the resignation of Urjit Patel as a setback to the convergence that the central bank and the government were reaching on contentious issues. He termed Urjit Patel's resignation as "shock" and said he will be missed. "Surprised at the news that RBI governor has resigned," he said in a tweet. The November 19 board meeting of the RBI was held in "such cordial atmosphere" that the resignation comes as a "shock", Mr Gurumurthy said.
