Chacko has received a go-ahead from the Congress high command to convene a meeting of the committee to adopt the draft report.
Besides 15 members from BJP, JD (U), Left parties, Trinamool Congress, AIADMK, DMK and BJD, UPA outside supporter Samajwadi Party is also opposed to the draft which has given a clean chit to Prime Minister Manmohan Singh and Finance Minister P Chidambaram in 2G spectrum allocation.
With the number clearly not on his side in the 30-member committee, Chacko wants the members opposed to the draft to give dissent notes. He is not willing to alter the text of the draft.
Sources said if he fails to convene a meeting before Parliament adjourns sine die, he would move the Speaker seeking an extension. Since he needs the backing of the committee to go for an extension, it is necessary that he convenes a meeting to approve the resolution for extension.
