The Election Commission barred both Trinamool Congress factions from using the original party name and 'Jora Ghash Phul' symbol for the October 6 bypolls.
The Mamata Banerjee faction was assigned the 'Football Player' symbol, while the rebel group led by Ritabrata Banerjee received the 'Envelope' symbol.
Mamata Banerjee criticized the decision as an unconstitutional move motivated by political vendetta, while CJP co-convenor Saurav Das mocked the new 'Envelope' symbol.
