Earlier, eminent writer and academic Md Zafar Iqbal and professor Hasina Khan have expressed their disappointment over the plagiarised contents found in the textbooks for the seventh grade edited by themselves.

The writers associated with editing the book also accepted their responsibility in a statement issued on Monday.
