Ending their boycott, Bharatiya Janata Party (BJP) members attended the Joint Parliamentary Committee (JPC) panel's meeting on the 2G spectrum scam that ended inconclusively here on Thursday, media reports said.
According to reports, the BJP and the Left members demanded having Prime Minister Manmohan Singh and Union Finance Minister P Chidambaram as witnesses in the case.
The BJP members earlier said the deposition of former Cabinet Secretary K M Chandrasekar gave enough evidence to call Singh and Chidambaram.
JPC Chairman P C Chacko, however, ruled out calling Singh for deposition.
A body of GSM operators appeared before the JPC on Thursday to give the telecom operators´ view before the finalisation of the report.
The BJP earlier stayed away from the JPC panel´s meeting on the 2G scam in demand that Chidambaram must depose before it.
The BJP members, who are part of the JPC examining the 2G spectrum allocation scandal, walked out of a meeting of the panel on Sept 18 as their demand of finalising the list of witness in connection to the case was rejected.
Touted to be the biggest corruption scandal of independent India, the 2G scam, allegedly masterminded by former telecom minister A Raja, pertains to a biased distribution of mobile airwaves and operating licenses, in lieu of kickbacks, to telcos that could have cost the treasury up to Rs 1.76 lakh crore in lost revenue, according to the government´s auditors CAG.
The court on May 15 granted bail to Raja who was languishing in the Tihar jail for 15 months in the 2G case.
