BJP members said they would again press for finalising the list of witness and calling Prime Minister Manmohan Singh, Finance Minister P Chidambaram and former Telecom Ministers A Raja and Dayanidhi Maran before JPC.
Accusing Congress members of using "foul language", five of the six members had walked out of JPC proceedings on August 22. A war of words had broken out between BJP and Congress members over calling of the Prime Minister and Chidambaram as witnesses.
Since then, JPC has not met though its chief P C Chacko had decided to start calling "essential witnesses" even if BJP kept away from the proceedings.
The appearance of Subbarao, who was Finance Secretary between April, 2007 and September, 2008, is significant as he had questioned the Department of Telecom on the issue of entry fee.
