The resignation of Ghulam Nabi Azad on Friday triggered a barrage of reactions from his Congress colleagues, many of them reminding him of the various positions he enjoyed in the party and questioned the timing of the letter just ahead of the Bharat Jodo yatra against the BJP.
Following Mr Azad's resignation, eight loyalists from the Jammu and Kashmir unit, including thee Ministers resigned in solidarity.
Digvijaya Singh said Mr Azad may have written the letter as he has become close to those who removed article 370 from J&K.
