Netaji Subhas Chandra Bose's grand-nephew, Chandra Kumar Bose, on Monday, 3 August resigned from the All India Trinamool Congress (TMC), barely four months after formally joining the party. In a letter addressed to TMC supremo Mamata Banerjee, Bose cited personal reasons for his exit, making no reference to any political dispute.
The Resignation
In his letter, Bose wrote: 'I hereby tender my resignation from the primary membership of the All India Trinamool Congress with immediate effect, due to personal reasons. I wish you and the AITC all the very best in all its future endeavours.' The resignation takes effect immediately, according to the letter.
Bose had been officially inducted into the party at Trinamool Bhavan on 12 April, marking a high-profile addition for the TMC ahead of anticipated electoral contests in West Bengal.
A Political Journey Marked by Reversals
Bose's departure from the TMC is the latest chapter in a turbulent political trajectory. He had originally joined the Bharatiya Janata Party (BJP) in 2016 at a rally in Howrah, in the presence of Union Home Minister Amit Shah. In the 2019 Lok Sabha elections, he contested from the Kolkata Dakshin constituency on a BJP ticket but lost to TMC candidate Mala Roy.
Following that defeat, Bose gradually distanced himself from the BJP. After the 2021 West Bengal Assembly elections, he withdrew entirely from active party politics. When he eventually crossed over to the TMC earlier this year, he described his original decision to join the BJP as a 'mistake'.
The SIR Hearing and Disillusionment with BJP
A key trigger for Bose's estrangement from the BJP was reportedly his summons for a Special Intensive Revision (SIR) hearing, which raised questions about his citizenship. Bose publicly questioned why his citizenship was in doubt given that he is the grand-nephew of freedom fighter Netaji Subhas Chandra Bose — a sentiment that deepened his disillusionment with the party at the Centre.
TMC's Internal Split Adds Context
Bose's exit also comes amid significant turbulence within the TMC itself. Following a change of government in West Bengal, the party has reportedly split, with a majority faction aligning with a rebel camp of MLAs led by Ritabrata Banerjee, the Leader of the Opposition in the state Assembly. Former Chief Minister Mamata Banerjee now leads what is described as the original but minority faction of the party.
Rather than align with either faction in the fractured party, Bose chose to exit entirely — a decision that underscores his reluctance to be drawn into the ongoing internal power struggle. With no party affiliation now, Bose's next political move remains to be seen.
Point of View
Away by 2021, TMC in April, out by August — reflects a broader crisis of political identity among figures who carry symbolic capital but lack organisational roots. His departure is also a signal of how toxic the TMC's internal split has become: even a high-profile recruit with the Bose family name chose to walk away rather than pick a side. The SIR citizenship episode, which Bose himself raised publicly, remains unresolved and could yet become a political flashpoint. Mainstream coverage has focused on the resignation letter; the more consequential question is whether Bose re-enters politics independently, and what that means for the Netaji legacy in Bengal's electoral arithmetic.
