The CBI on Wednesday told a special court that former telecom minister A Raja had misled the then Prime Minister Manmohan Singh on policy matters pertaining to 2G spectrum allocation.

Raja had deliberately advanced the cut off date to favour accused firms in 2G allocation, CBI told court, adding, 2G spectrum was granted to "ineligible" companies like Swan Telecom Pvt Ltd and Unitech Wireless (Tamil Nadu) Ltd.

CBI made these charges during the final arguments in the 2G spectrum allocation scam case.

In its chargesheet, CBI had alleged that there was a loss of Rs 30,984 crore to the exchequer in allocation of 122 licences for 2G spectrum which were scrapped by the Supreme Court on February 2, 2012.

The court has recorded statements of 154 CBI witnesses, including Reliance ADAG Chairman Anil Ambani, his wife Tina Ambani and former corporate lobbyist Niira Radia, running into over 4,400 pages in the case.
