Three former Trinamool Rajya Sabha MPs have joined the BJP in Bengal, which may be seen as a setback for Mamata Banerjee. The former MPs, who include Sushmita Dev, Sukhendu Sekhar Ray, and Prakash Chik Baraik, are expected to contest Rajya Sabha bypolls from the seats they vacated. The BJP has defended its decision to induct the former MPs, citing their clean record.
