A key internal meeting of the Congress tomorrow will discuss a letter written by more than 20 top leaders of the party that has pointed to the deep crisis within and sought sweeping reforms. The letter, signed by senior leaders like Kapil Sibal, Shashi Tharoor, Ghulam Nabi Azad, Prithviraj Chavan, Vivek Tankha and Anand Sharma, pointed to the steady decline of the party as the country faces its "gravest political, social and economic challenges since Independence". While calling for a "full-time", "visible" leadership, the letter also praised the leadership provided by the Gandhis over the years.
