Amidst the ongoing Rafale jet controversy, which has spiralled into a major national debate, a delegation of senior Congress leaders met the Central Vigilance Commissioner (CVC) on Monday and demanded registration of a case in the alleged corruption in the nearly Rs 58,000 crore deal.

The delegation comprising senior Congress leaders Ghulam Nabi Azad, Ahmed Patel, Anand Sharma, Kapil Sibal, Randeep Singh Surjewala, Jairam Ramesh, Abhishek Manu Singhvi, Manish Tewari, Vivek Tankha, Parmod Tiwari and Pranav Jha met CVC K V Chowdary and submitted a detailed memorandum, accusing the government of causing loss to the public exchequer and endangering national security by bypassing state-run Hindustan Aeronautics Limited (HAL) in favour of some businessman "friends" for offset contract.

The meeting comes days after a Congress delegation met the Comptroller and Auditor General (CAG) and urged the apex auditor to prepare a report on the alleged irregularities in the deal and present it in Parliament.

The Congress has launched an offensive against the BJP government over the Rafale deal, alleging corruption and violation of rules by Prime Minister Narendra Modi and demanded answers from him.

It has also accused the prime minister, the finance minister and the defence minister of "lying on the issue".

The Rafale controversy took a turn last week after former French president Francois Hollande claimed that the Indian government proposed Reliance Defence's name as the offset partner for Dassault Aviation.

Modi had announced the procurement of 36 Rafale fighters after holding talks with the then French president Hollande on April 10, 2015, in Paris.
