Karti Chidambaram arrives at the Enforcement Directorate office to appear in connection with INX Media case. 

And right at this very moment, Robert Vadra has also arrived at the ED office for the second day of questioning. 

Karti Chidambaram, who is the son of former Finance Minister P Chidambaram, has been questioned on several occasions in the case being probed by the ED as well as the Central Bureau of Investigation.

Both the agencies are probing how Karti Chidambaram managed to get clearance from the Foreign Investment Promotion Board (FIPB) in 2007 when his father was the Finance Minister.

On February 28, 2018, Karti was arrested by the CBI for allegedly accepting money to facilitate the FIPB clearance to INX Media. He was later granted bail.

Vadra, who was questioned on Wednesday for more than five hours by the Enforcement Directorate, has denied owning properties in London or knowing any of the people the agency says were involved in the deals, sources said.
