NEW DELHI: The ED again questioned former finance minister P Chidambaram for about six hours today in the Aircel-Maxis money laundering case, officials said.

Sources said Chidambaram's statement was recorded under the Prevention of Money Laundering Act (PMLA) after he appeared before the investigating officer (IO) of the case at the Enforcement Directorate 's office here.

The questioning went on for about six hours, they said.

While the CBI has filed a chargesheet in this case involving the Congress leader in July, the ED is expected to file its own prosecution complaint within the next fortnight.

It is understood that the agency wanted to put a fresh set of questions to him regarding the deal and hence had asked him to appear.

The agency had earlier recorded statements of officials who were in FIPB when this deal took place, and it is understood that Chidambaram would have been confronted with these versions.

Some specific queries on the circumstances and procedures adopted by the now-defunct Foreign Investment Promotion Board (FIPB), while giving approval to the Aircel-Maxis deal during his tenure, were put to him earlier.

His son Karti has also been questioned by the ED in this case twice.

Chidambaram, after a similar questioning by the ED in this case in June, had said that what he told the agency was already recorded in government documents. He also said that there is no FIR, yet a probe had been initiated.

"More than half the time taken up by typing the answers without errors, reading the statement and signing it!," he had said in his tweet.

The Aircel-Maxis cases pertains to grant of Foreign Investment Promotion Board clearance to firm M/S Global Communication Holding Services Ltd in 2006 for investment in Aircel .

The Supreme Court had on March 12 directed investigating agencies — the CBI and the ED — to complete their probe into the 2G spectrum allocation cases, including the Aircel Maxis alleged money laundering case, in six months.

The agency had said that the FIPB approval in the Aircel-Maxis FDI case was granted in March 2006 by Chidambaram even though he was competent to accord approval on project proposals only up to Rs 600 crore and beyond that it required the approval of the Cabinet Committee on Economic Affairs (CCEA).

The ED is investigating "the circumstances of the FIPB approval granted (in 2006) by the then finance minister".

"In the instant case, the approval for FDI of USD 800 million (over Rs 3,500 crore) was sought. Hence, the CCEA was competent to grant the approval.

"However, the approval was not obtained from the CCEA," the ED had alleged.

The agency said its probe revealed that the case of the said FDI was "wrongly projected as an investment of Rs 180 crore so that it need not be sent to the CCEA to avoid a detailed scrutiny".

The ED is probing the Aircel-Maxis deal under the PMLA after taking cognisance of a 2011 CBI FIR in the case.

The senior Chidambaram had earlier described the ED action in this case as a "crazy mixture of falsehoods and conjectures" and said that the charge sheet filed by probe agencies was rejected by the court.

However, the agencies maintained that the FIR in the case had not been quashed.

In September last year, the ED had attached assets worth Rs 1.16 crore of Karti and a firm allegedly linked to him in connection with this case.
