Months before elections in Rajasthan, the fault lines in the state's Congress unit came to the fore on Sunday, as party leader Sachin Pilot opened a fresh line of attack on his rival, Chief Minister Ashok Gehlot, announcing that he will sit on a one-day fast against corruption on Tuesday. The 45-year-old leader has demanded that the Gehlot government act against the alleged corruption of the previous BJP government led by Vasundhara Raje.
