Chandra Kumar Bose, a direct descendant of freedom fighter Netaji Subhas Chandra Bose, on Monday quit the Mamata Banerjee-led faction of the Trinamool Congress (TMC).
The exit over "personal reasons" makes him the latest leader to leave the Mamata camp, which has already seen a steady exodus of leaders since Ritabrata Banerjee's high-profile jump alongside 59 other party MLAs.
"I hereby tender my resignation from the primary membership of the All India Trinamool Congress with immediate effect, due to personal reasons," read his letter to the TMC supremo.
This comes after the longtime BJP leader had joined the TMC just before the latter lost badly in the 2026 Assembly elections that saw Suvendu Adhikari rise to power and take the CM post from Mamata.
Back in April this year—one month away from the Assembly polls—the Netaji descendant had joined the TMC, calling for a more inclusive political approach, saying that joining the saffron party had been one of the biggest mistakes of his political life.
Exit from the BJP
Hailing from one of India's most prominent political families, Chandra Kumar Bose is the son of Amiya Nath Bose, a former MP and noted lawyer, and the grandson of Sarat Chandra Bose, a senior Congress leader, barrister and elder brother of Netaji Subhas Chandra Bose.
He is said to have carved a niche for himself in the business world before entering politics, having worked for Tata Steel for 18 years, after which he started his own IT firm in 2004.
He is also the leader of the Open Platform for Netaji, a collective aimed at declassifying secret documents related to the freedom fighter.
His career with the BJP began in 2016, when he contested and lost the Assembly elections for them from Mamata Banerjee's stronghold of Bhabanipur.
He then contested the 2019 Lok Sabha polls, rising to the position of the party's vice-president in the state before he resigned in 2023 over multiple differences with the saffron party, especially on the Citizenship Amendment Act (CAA) issue.
At the time, he had said that he was unable to fulfill Netaji's inclusive nationalist ideology under the BJP, which is why he called it one of the biggest mistakes of his political life, and then joined the TMC in 2026.
The Trinamool Congress has yet to respond to his exit from the Mamata camp after just four months.
