The Congress's Rahul Gandhi -- who quit the party top post last year -- is firm on his stand not to accept it again, sources close to him told NDTV. Priyanka Gandhi Vadra is also clear she will remain as a general secretary and not take on a bigger role, sources said as the Congress, fresh out of the Rajasthan crisis, found itself caught in a huge controversy. A letter by more than 20 leaders demanding an overhaul of the party leadership and its functioning -- written as Priyanka Gandhi Vadra was helping solve the Rajasthan crisis -- has become public.
