Amid reports of interim chief Sonia Gandhi offering to quit in the wake of a letter by a group of leaders demanding a change in the Congress leadership and reforms in the party, the "palace coup" has intrigued workers and leaders alike and all eyes are on the Monday meeting of the Congress Working Committee.
