The 12-hour Trinamool-sponsored bandh in Kolkata has been largely successful. Most schools and colleges remained closed. In many areas, shops and markets also remained shut. The bandh has been called in protest against the price hike of fuel and other commodities. The Kolkata High Court had already declared the Trinamool-sponsored bandh illegal and unconstitutional. Trinamool Congress chief Mamata Banerjee ended the bandh two hours before the scheduled time. There is speculation about why the bandh was successful.
