The 2G controversy rocked Parliament's Public Accounts Committee (PAC) meeting in Delhi today with opposition parties demanding that former DG (Audit) R P Singh be summoned and asked why he differs with CAG on the quantum of loss while Congress members opposed the move.

With differences persisting, the meeting was adjourned. The meeting scheduled for tomorrow has also been postponed reportedly on as Chhath festival falls tomorrow. 

Sources said the BJP and other opposition parties insisted that Singh should be summoned as he has differed with the figures of loss incurred by the government in the 2-G scam.

Singh, who has now retired, has stated that the loss is merely of Rs 6,000 crore while the CAG had maintained that itwas to the tune of Rs 1.76 lakh crore.
