MUMBAI, July 27: The Bharatiya Janata Party (BJP on Tuesday lambasted Swaraj Kaushal, the former central government interlocutor in the Naga peace talks. The party has accused him of exceeding his brief. PB Acharya, BJP national secretary in charge of the Northeast states, lashed out at Kaushal saying that Kaushal was an interlocutor of the government in the Naga peace talks and "not the government itself". Taking exception to the article written by Kaushal wherein he had said that the Prime Minister had not respected him for his words, Acharya said that the decision of Kaushal to extend the ceasefire agreement beyond Nagaland had dangerous implications.
