The Enforcement Directorate (ED) is probing the merger of Air India and Indian Airlines and the acquisition of 111 aircraft for alleged money-laundering during the UPA-1 era, The Indian Express reported on Saturday. The ED probe has come more than a year after the\u00a0Central Bureau of Investigation (CBI) began investigating the deals. According to the report, which quotes unidentified ED officials, NCP leader\u00a0Praful Patel was the Civil Aviation Minister when the said merger took place. He, however, has denied any wrong-doing and said that all decisions taken with regard to the merger were "collective". Last year, four CBI FIRs were lodged under provisions of Prevention of Money Laundering Act (PMLA). "While probing a case of money laundering against corporate consultant Deepak Talwar, we stumbled upon some money trail that is linked to the entire matter of Air India. We have traced a payment linked to the Air India case to an entity linked to Deepak Talwar. The money involved is huge," The Indian Express quoted a senior ED official as saying. Notably, Deepak Talwar is being probed in connection with alleged misuse of funds at his NGO\u00a0Advantage India under\u00a0Foreign Contribution Regulation Act (FCRA). He was not available for comments, the national daily said. In January 2012, the\u00a0Comptroller and Auditor General (CAG) had highlighted irregularities in the deals and called the decision to\u00a0acquire 111 planes for Air India through debt "a recipe for disaster". The CAG also called the merger of the state-run carriers "ill-timed". "This was a recipe for disaster ab initio and should have raised alarm signals in Ministry of Civil Aviation, Public Investment Board and the Planning Commission," the CAG report had said.
