"Former MP of Ambedkar Nagar, Tribhuvan Dutt, will be replacing Ramesh Gautam," party's national general secretary Naseemuddin Siddiqui said during a meeting of party workers here today.
Dutt had been jailed in a criminal case.
Siddiqui attacked the SP government, alleging that law and order has collapsed in the state and there was a "rule of goons and mafias".
He called upon the party workers to prepare for the Lok Sabha elections.
