The Election Commission has imposed an interim freeze on the use of the Trinamool Congress (TMC) name and its election symbol. The decision comes ahead of upcoming by-elections, amid an ongoing dispute between the factions of Mamata Banerjee and Ritabrata Banerjee over control of the party. The order is being seen as a major setback for both factions, as the party's name and symbol cannot be used until the dispute is resolved.
