The CBI on Thursday filed a supplementary charge sheet against senior Congress leader P. Chidambaram, and his son, Karti Chidambaram, naming them accused in the Aircel-Maxis deal case.
The charge sheet was filed before special CBI judge O. P. Saini, who has fixed July 31 for considering the document.
Mr. Chidambaram's role had come under the scanner of investigating agencies in the Aircel-Maxis deal of Rs. 3,500 crore and INX Media case involving Rs. 305 crore.
It was during his tenure as the Union Finance Minister in the UPA-I government that the Foreign Investment Promotion Board (FIPB) granted clearance to the two ventures in which alleged irregularities have been found.
