Earlier, the ED dropped a bomb by mentioning that the name of 'Mrs Gandhi' has come during questioning of Christian Michel in connection with the case.

In a development which can have far-reaching political implications, the Enforcement Directorate (ED) has claimed that a person with abbreviations 'RG' received Rs 50 crore between 2004 to 2016 in connection with AgustaWestland deal.

The sensational revelation has been made by the ED while seeking remand of accused Sushen Gupta. "Sushen Gupta is misguiding the investigation by deliberately giving wrong abbreviations in his diaries wherein abbreviation 'RG' find mention in many pages as well as in pen drive data," stated the ED application, a copy of which is available with India Today TV.

"More than 50 crore is shown to have been received by 'RG' in between 2004 to 2016 whereas the 'RG' identified by Sushen Gupta i.e. Rajat Gupta had admitted to have cash transaction with Sushen Gupta from 2007 onwards and the same is being quantified," the ED application stated.

To check the veracity of Sushen's claims, the ED said it has questioned Rajat Gupta.

"I have no concern with abbreviation 'RG' and only he (Sushen Gupta) can explain," Rajat Gupta said in his statement to ED.

The Enforcement Directorate believes that Sushen Gupta is deliberately not disclosing who 'RG' is.

Earlier, the ED dropped a bomb by mentioning that the name of 'Mrs Gandhi' has come during questioning of Christian Michel in connection with the case.

A supplementary chargesheet has been filed against middleman Michel on Thursday before the Patiala House Court. The chargesheet includes Michel's statement and an affidavit. Sources say, the chargesheet is going to be very crucial and create a problem for certain politicians and former bureaucrats.
