The Enforcement Directorate has summoned former Union minister P Chidambaram in connection with its money-laundering probe in the alleged purchase of 111 Air India aircraft during the UPA regime, officials said on Monday.
The law enforcement agency said the former finance minister has been asked to depose on August 23 before the investigating officer of the case to record his statement.
The case pertains to losses suffered by the national carrier due to an alleged multi-crore aviation scam and irregularities in fixing air slots for international airlines.
Former aviation minister Praful Patel was previously grilled by the ED and it is understood that the agency now wants to question Chidambaram on their leads in this case.
Besides this scam, the senior Congress leader is also being probed in two separate money laundering cases of Aircel-Maxis and INX Media.
