Beware of a friend who turns foe, they say. He is more dangerous than most. And both Chhagan Bhujbal and Narayan Rane are proving equal to the task. One, the deputy chief minister of Maharashtra and the other a former chief minister, both grew up together in the Shiv Sena, and are now ranged on opposite sides of the political fence in the state. Since the time he quit the Sena for the Congress and now Sharad Pawars Nationalist Congress Party, Bhujbal has done untold damage to his former boss, Bal Thackeray. Rane thought he might just return the compliment.
