Mamata Banerjee-led TMC suffered another setback as Rajya Sabha MP Prakash Chik Baraik resigned from Upper House, becoming the third party MP to quit within a week after Sukhendu Sekhar Ray and Sushmita Dev. His exit will reduce TMC's strength in Rajya Sabha to 10. This comes amid reports that around 20 Trinamool MPs have offered support to BJP-led NDA.
