Sushmita Dev and two other former Trinamool Congress MPs have joined the BJP, which may pose a challenge for Mamata Banerjee. The exact circumstances and potential implications of their move are unclear, but it appears to have occurred ahead of upcoming Rajya Sabha bypolls. The names of the other two former MPs who joined the BJP are reported differently across outlets, with some mentioning Prakash Chik Baraik and Sukhendu Sekhar Roy.
