Is Trinamool Congress heading for vertical split?

The Trinamool Congress faces a potential vertical split as a rebel faction claiming support from twenty parliamentarians threatens to defect to the central ruling coalition. Internal tensions escalated after lawmakers skipped strategy meetings, citing lack of development and a medical college controversy. In response, party leadership challenged dissidents to resign. Simultaneously, the Criminal Investigation Department served a notice at Mamata Banerjee’s residence regarding a signature forgery case involving Abhishek Banerjee. At Kolkata airport, MP Kalyan Banerjee engaged in a verbal altercation with onlookers. In Kerala, health authorities are monitoring a Shigella bacterial infection outbreak following a child's death in Kozhikode and hundreds of symptomatic cases in Wayanad. Meanwhile, a severe water crisis persists in Delhi and Hyderabad, where residents report sewage-contaminated water. Additionally, Union Ministers Dharmendra Pradhan and JP Nadda reviewed security protocols for the National Eligibility cum Entrance Test re-examination scheduled for June 21 to prevent paper leaks and ensure coordination with state governments.
