Former Finance Minister P. Chidambaram on Friday said another Rs 50,000 crore should be added to the cost of the note ban exercise that was undertaken last year.

"Cost of demonetisation: Add another Rs 50,000 crore revealed by RBI," he tweeted in the wake of an RBI statement that it would pay Rs 30,659 crore as dividend to the government in 2016-17, less than half of the dividend transferred a year earlier.

He also asked whether RBI would reveal the breakdown of the Rs 50,000 crore "loss/expenditure".

"Will RBI also tell us cost of destroying old notes and cost of printing new/replacement notes," Chidambaram asked in another tweet.
