Party spokesperson Sambit Patra said the 125 crore people of India will never forgive anyone calling the Prime Minister an ISI agent.
"When Modi is spreading his message against terrorism in the world, we saw that recently in Saudi Arabia, then for an elected representative to say so is shameful and unfortunate," he told reporters.
Such use of words for a Prime Minister for "cheap politics and lust of power" amounted to insult of Indian people, he said.
At a press conference, Kejriwal had said Modi's "invitation" to Pakistani JIT, which included an ISI official, amounted to giving a "clean chit" to the spy agency for the Pathankot attack and demanded that he tender an "apology" for the "monumental" foreign policy failure.
