"Yogendra Yadav who was the chief advisor of the Textbook Development Committee and Suhas Palshikar who was the member of the committee have resigned," sources in the HRD Ministry said.
Palshikar said he has quit the advisor council in the wake of the uproard in Parliament over the issue.
Sources in NCERT said they were already in the process of constitution of a new committee.
They said the cartoon used in the class XI social science textbook 'Indian Constitution at Work' was actually sketched back in 1948 by Keshav Shankar Pillai when the framing of the constitution was in process.
Sibal had clarified in Parliament that the textbooks are made by an independent textbook authority - Textbook Development Committee, which comprise academics and not officials of NCERT.
He said none of the existing members of the present Textbook Committee, which had approved the book, will be part of the new Committee set up to examine objectionable caricatures.
