# West Bengal Trinamool Congress internal crisis > Live situation record from CLSTR: https://clstr.news/situations/murder-of-suvendu-adhikaris-aide-fuels-political-clash-ahead-of-his-west-bengal-chief-minister-swear > Updated: 2026-08-28T12:23:45.000Z. Sources: 150. Developments: 153. The internal crisis within the Trinamool Congress (TMC) has intensified as legal and political disputes over party control continue. In late July 2026, Mamata Banerjee urged the Election Commission to conclude its inquiry into the party’s name, symbol, and organizational control, warning that further extensions to the rival faction led by Ritabrata Banerjee could allow for the fabrication of false evidence. Political tensions with the ruling BJP have also escalated. Banerjee accused the BJP of insulting the legacy of Netaji Subhas Chandra Bose following comments made by the state BJP president regarding the Forward Bloc. Amidst this friction, Chandra Kumar Bose, the grandnephew of Netaji, resigned from the TMC. Further instability has emerged within the rebel bloc of 20 MPs who had pledged support to the NDA. Three MPs—Khalilur Rahaman, Abu Taher Khan, and Yusuf Pathan—skipped an NDA parliamentary meeting, with Khan stating, “We are not with the NDA, nor are we joining the BJP.” This development highlights ongoing uncertainty regarding the group’s status under anti-defection laws. In late August 2026, Banerjee used Facebook Live to deny rumors of retirement, stating her goal is to continue her struggle until the BJP is marginalized. She accused the administration of using the census as a covert attempt to implement the National Register of Citizens and claimed that approximately 75 percent of women have stopped receiving Annapurna Bhandar payments. Banerjee also alleged that Suvendu Adhikari threatened to ensure she could not leave her home, prompting her to call for intervention from the President of India and the Chief Justice of the Supreme Court. During a rally in Kolkata, Banerjee accused the BJP of seizing power through ‘theft’ and vowed that the TMC would return to power. ## Claims - The Election Commission set a deadline of 6 July 2026 for the TMC to submit its response to the dispute. (disputed) - The commission gave Ritabrata Banerjee an initial deadline of 10 July 2026, later extending it to 25 July 2026 after a request. (disputed) - Mamata Banerjee stated she has no intention of retiring from politics. (corroborated by 4 sources) - The BJP government is cutting the number of beneficiaries for the Annapurna Bhandar scheme using ineligibility as a pretext.

(corroborated by 2 sources) - Suvendu Adhikari threatened to ensure Mamata Banerjee cannot leave her house.

(corroborated by 2 sources) - Mamata Banerjee wrote a letter to Election Commission Secretary Ashwani Kumar Mohal urging the commission to conclude the inquiry into the TMC's name, symbol and organisational control. (single source) - The inquiry concerns a dispute between the TMC and a rival faction led by Ritabrata Banerjee. (single source) - The TMC submitted its response on 6 July 2026 and sent a copy to Ritabrata Banerjee via email and speed post. (single source) - As of 25 July 2026, the Election Commission had not informed the TMC whether Ritabrata Banerjee had submitted a reply, nor provided a copy if he did. (single source) - Mamata Banerjee argued that further extensions would allow the rival faction to fabricate false evidence and stressed that the dispute has serious political ramifications in West Bengal.
