After Kapil Sibal openly attacked the Congress leadership over the party's poor show in the Bihar Assembly polls, former Foreign Minister Salman Khurshid on Tuesday used couplets of last Mughal emperor Bahadur Shah Zafar and said that if "we are explicitly or implicitly willing to compromise with the principles to regain power, we might as well pack up our bags".

"The constant refrain of some persons should not be of aimless introspection, but for reaffirmation of fundamental principles we believe in," Khurshid said.
