New Delhi: A day before submission of the audit report on military procurement, including the Rafale jet deal, by the Comptroller and Auditor General (CAG) of India to the President, the Congress on Sunday citing a "conflict of interest" said the exercise is a cover-up of the "scam".

Holding Prime Minister Narendra Modi "guilty" of compromising national security, the Congress also criticised the Bharatiya Janata Party (BJP)-led central government for being "opaque, intransient, obscure and obstinate to cover up the layers of corruption in the Rafale scam".
