"There are complaints about the procedure of calculating the Life Cycle Cost and that issue is not yet settled. Before bringing the deal before the Cabinet Committee on Security for final approval, we would like to get clear on that aspect," he told a press conference here.
Antony hoped that deal will be finalised in 2014-15.
French Rafale fighter aircraft has been the lowest bidder in the medium-multirole combat aircraft deal, which is touted as the "mother of all deals" and is expected to cost India more than Rs 60,000 crore.
Senior BJP leader and former finance minister Yashwant Sinha has written to Antony raising a number of questions over the "conceptual shift" in the defence procurement policy and expressed fears that the LCC concept may bring in corruption.
Asserting that the negotiations in the deal were still progressing, the Defence Minister said the financial condition of the government was not good and "there is no money for this."
Asked whether the Government would buy more Su-30MKI combat aircraft from Russia if the deal with the French aircraft manufacturer does not fructify, Antony expressed hope that, "The M-MRCA will materialise next year."
He said the Government was making headway in the deal and taking all the possible care in the process to ensure that there are no loose ends in the "mother of all deals".
After a five-year long process, India had selected the French Dassault Aviation last year for meeting its requirement for 126 combat aircraft edging out the European consortium EADS' Eurofighter Typhoon fighter jet.
