New Delhi, Jul 26 - Former Telecom Minister A Raja today dragged Prime Minister Manmohan Singh again in the 2G case, alleging he too could be held guilty of "conspiracy" and dereliction of duty for not forming a GoM to examine the spectrum allocation issue. Raja's submission before a court came just hours after the DMK MP said he did not seek to implicate Manmohan Singh and former finance minister P Chidambaram in the 2G case on the basis of his arguments yesterday.
