"Resignation of Maran has to happen. Certainly his position has become untenable," party spokesperson Nirmala Sitaraman told reporters here after the CBI told the Supreme Court that the minister has come under its scanner in the 2G spectrum allocation scam.
The BJP leader said it needed to be seen whether the naming of ministers allegedly involved in the scam would stop with the alliance partners only or more names would come out.
"It is also appropriate to ask questions whether this will stop only with the alliance partners only or if there are more people which the current Cabinet holds or there are reasons for explanation on the decisions taken at that time," she said.
In its 71-page fresh status report about the scam, the CBI said that during 2004-07 when Maran was telecom Minister, a Chennai base telecom promoter (Sivasankaran) was forced to sell the stake in Aircel to a Malaysian firm.
