Lucknow: A Congress legislator in Uttar Pradesh on Thursday raised the banner of revolt against the nomination of P.L. Punia as the party candidate for the Rajya Sabha elections scheduled later this month.

Three-time legislator from Gonda Sadar, Vivek Singh, shot off a terse letter to Congress vice-president Rahul Gandhi and said many leaders supposedly close to him were sabotaging the party's prospects in the state.
