BJP MP Subramanian Swamy on Thursday appeared to target Economic Affairs Secretary Shaktikanta Das, which prompted Finance Minister Arun Jaitley to call it an "unfair and false" attack on a disciplined civil servant.

"I think there a property deal case pending against him (Das) for assisting PC swallow Mahabalipuram prime locations," Swamy tweeted today.

It was in reply to his twitter handle followers who had sought blacklisting of RBI Deputy Governor Urjit Patel and Das from RBI Governorship as well as sending Das back to his parent cadre Tamil Nadu.

Shortly thereafter, Jaitley, who is in China, tweeted, "An unfair and false attack on a disciplined civil servant in the Finance Ministry."

Jaitley had yesterday led a strong defence of Chief Economic Adviser Arvind Subramanian after Swamy had attacked him, and rued how far politicians can go to attack those in government whose discipline and constraints of office restrain them from responding.

The Minister is in China to attend the Asian Infrastructure Investment Bank (AIIB) Board of Governor's meeting.
