The '''2026 Trinamool Congress (AITC) split''' refers to the fracturing of the regional party that had governed [[West Bengal]] for fifteen consecutive years, into two rival factions in June 2026. The rupture created the [[Mamata Banerjee]]–[[Abhishek Banerjee (politician)|Abhishek Banerjee]] bloc (later renamed as [[Mamata All India Trinamool Congress]] with symbol "''football player''") and the [[Ritabrata Banerjee]]–[[Sandipan Saha]] bloc ([[Democratic Trinamool Congress]] with symbol "''envelope"'') within the party following its defeat in the [[2026 West Bengal Legislative Assembly election|2026 West Bengal polls]]. [[Trinamool Congress|AITC]] was established in 1998, and the [[Election Commission of India]] recognises it as a regional party.

One faction of the party remained loyal to its founder and chairperson, Mamata Banerjee, and her nephew and general secretary, Abhishek Banerjee. The other—led by Ritabrata Banerjee and fellow [[Member of the Legislative Assembly (India)|Member of Legislative Assembly (MLA)]] Sandipan Saha—positioned itself as the party's legislative wing in the new assembly and aligned with the [[Bharatiya Janata Party]]-led [[National Democratic Alliance]].

== Background ==

On 4 May 2026, after the [[2026 West Bengal Legislative Assembly election|2026 West Bengal assembly polls result]] was declared, 15-year ruling AITC government led by the founder-chairperson of the party and then [[Chief Minister of West Bengal]], Mamata Banerjee lost the power from the state and for the first time, the India's ruling party, Bharatiya Janata Party came to power in the state with former Trinamool leader and once Mamata's close aide [[Suvendu Adhikari]] succeeding as Chief Minister on 9 May, after Mamata. Mamata Banerjee herself lost her seat, [[Bhabanipur, West Bengal Assembly constituency|Bhabanipur]], to her successor, Adhikari.<ref>{{Cite web|url=https://www.ndtv.com/india-news/mamata-banerjee-loses-bhabanipur-stronghold-to-suvendu-adhikari-11448550|title=Mamata Banerjee Loses Bhabanipur Stronghold To Suvendu Adhikari|date=4 May 2026|access-date=5 May 2026|work=[[NDTV]]}}</ref><ref>{{Cite web|url=https://www.hindustantimes.com/india-news/mamata-banerjee-vs-suvendu-adhikari-bhabanipur-election-result-2026-live-bjp-vs-aitc-who-will-win-ec-latest-updates-101777857219798.html|title=Bhabanipur election results highlights: Mamata loses Bhabanipur bastion to Suvendu by a margin of 15,000 votes|work=[[Hindustan Times]]|date=4 May 2026|access-date=4 May 2026}}</ref>

After the defeat, Mamata Banerjee called a meeting of winning candidates in her residence in [[Kolkata]], but out of 80 winning candidates, only 66 were present. Soon after, on 11 May, the party leadership declared former senior minister and newly elected AITC MLA from [[Ballygunge Assembly constituency|Ballygunge]], [[Sovandeb Chattopadhyay]], as the Leader of Opposition through a letter by Abhishek Banerjee, the party's General Secretary.<ref>{{Cite web|url=https://www.ndtv.com/india-news/sovandeb-chattopadhyay-ex-boxer-10-time-mla-now-bengals-opposition-leader-trinamool-congress-11477153|title=Sovandeb Chattopadhyay: Ex-Boxer, 10-Time MLA Now Bengal's Opposition Leader|work=[[NDTV]]|date=11 May 2026|access-date=12 May 2026}}</ref> But two AITC MLAs, namely Ritabrata Banerjee from [[Uluberia Purba Assembly constituency|Uluberia Purba]] and Sandipan Saha from [[Entally Assembly constituency|Entally]], allegedly complained to the Speaker of the Legislative Assembly, [[Rathindra Bose]], that the MLAs' signatures on the letter are forged. On 22 May, during CM Suvendu's tour to [[New Delhi]], Ritabrata and Suvendu held a secret meeting at Banga Bhawan.<ref>{{Cite web|url=https://www.indiatoday.in/india/story/trinamool-congress-split-ritabrata-banerjee-suvendu-adhikari-bengal-bhavan-meeting-2921725-2026-06-04|title=A Delhi corridor 'accidental' meet that triggered TMC's biggest split in 28 years|work=[[India Today]]|date=4 June 2026|access-date=6 June 2026}}</ref>

Meanwhile, many councillors in various municipalities such as [[Bhatpara]], [[Contai]], and [[North Barrackpur]] resigned. In [[Chandannagar]], the entire [[Chandernagore Municipal Corporation|municipal board]] was dissolved after councillors and the mayor resigned. Soon after, on 26 May, [[Member of Parliament, Lok Sabha|MP]] from [[Barasat Lok Sabha constituency|Barasat]], [[Kakoli Ghosh Dastidar]] resigned from various AITC organisational posts, taking responsibility for the party's defeat.<ref>{{Cite web|url=https://timesofindia.indiatimes.com/city/kolkata/tmc-mp-kakoli-ghosh-dastidar-steps-down-from-all-party-posts-amid-leadership-discontent/articleshow/131346188.cms|title=TMC MP Kakoli Ghosh Dastidar steps down from all party posts amid leadership discontent|work=[[The Times of India]]|date=27 May 2026|access-date=28 May 2026}}</ref><ref>{{Cite web|url=https://www.indiatoday.in/india/story/bengal-news-mamata-banerjee-barasat-mp-kakoli-ghosh-dastidar-resignation-2026-assembly-polls-tmc-defeat-barasat-mp-ipac-2916890-2026-05-25?utm_source=global-search&utm_medium=global-search&utm_campaign=global-search|title=Storm brewing in TMC?

===Split in the West Bengal Legislative Assembly===
Following the suspension of the rebel legislators, 60 MLAs declared their support for the [[Democratic Trinamool Congress|Ritabrata Banerjee-led faction]], which was subsequently recognised by Speaker Rathindra Bose as the principal opposition bloc in the [[West Bengal Legislative Assembly]]. Ritabrata Banerjee replaced Sovandeb Chattopadhyay as Leader of the Opposition.

On 22 June, the faction held a special session at which Arup Roy was elected chairperson<ref name=":1" /> and a 30-member National Working Committee was constituted, while the Mamata Banerjee-led faction continued to recognise Banerjee as party chairperson.

===Split in the Lok Sabha and merger with [[Nationalist Citizens Party of India|NCPI]]===
[[File:Kakoli Ghosh Dastidar flagging off the Howrah-Pune Suvidha AC Express from Howrah Station, West Bengal.jpg|left|thumb|Leader of Rebel MPs, [[Kakoli Ghosh Dastidar]]]]

Following the rebellion in legislative assembly,
a separate split occurred within the TMC's Lok Sabha parliamentary party. In June 2026, 20 of the party's 28 Lok Sabha MPs, led by Kakoli Ghosh Dastidar, broke away from the TMC parliamentary group and sought recognition as a separate bloc in the Lok Sabha. The group submitted a representation to Speaker Om Birla and announced that it would merge with the [[Nationalist Citizens Party of India]] (NCPI). The merger was accompanied by an announcement that the MPs would support the [[National Democratic Alliance]] (NDA) government at the centre. The rebel MPs also stated that they intended to continue their claim to the TMC's original name and election symbol before the Election Commission.

===Rajya Sabha split, resignation and BJP re-election===
The split was followed by a separate wave of resignations from the Rajya Sabha. Sukhendu Sekhar Roy resigned from both the TMC and his Rajya Sabha seat on 8 June 2026, citing the party's mismanagement during the election,<ref name=":2" /><ref>{{Cite web |date=2026-06-08 |title=Trinamool Rajya Sabha MP Sukhendu Sekhar Roy resigns, says ‘I was unhappy in party’ |url=https://indianexpress.com/article/cities/kolkata/trinamool-rajya-sabha-mp-sukhendu-sekhar-ray-resigns-says-i-was-unhappy-in-party-10729298/ |access-date=2026-09-18 |website=The Indian Express |language=en}}</ref> followed by Sushmita Dev and Prakash Chik Baraik in the following days.

On 2 July 2026, Ritabrata, Sandipan, and eight other MLAs went to Delhi to meet [[Chief Election Commissioner of India|Chief Election Commissioner]] [[Gyanesh Kumar]] to claim the party symbol and name, along with its funds.
On 17 September 2026, ahead of the by-elections announced for Nandigram and Rejinagar, the [[Election Commission of India]] (ECI) issued an interim order recognising the existence of two rival groups within the All India Trinamool Congress and froze the party's name and its reserved "Flowers and Grass" symbol pending a substantive determination under Paragraph 15 of the Election Symbols (Reservation and Allotment) Order, 1968<ref>{{Cite web |date=2026-09-17 |title=Trinamool name, symbol on interim freeze; factions told to pick new ones |url=https://indianexpress.com/article/india/election-commission-freezes-trinmool-congress-name-symbol-mamata-banerjee-ritabrata-banerjee-10882682/ |access-date=2026-09-18 |website=The Indian Express |language=en}}</ref>. The commission directed both factions to contest the by-elections under separate names and symbols. On 18 September, the ECI allotted the name [[Mamata All India Trinamool Congress]] and the "Football Player" symbol to the faction led by [[Mamata Banerjee]], while the faction led by [[Arup Roy]] was allotted the name [[Democratic Trinamool Congress]] and the "Envelope" symbol. The allotments were made as an interim arrangement for the by-elections and did not constitute a final determination of which faction was entitled to the original party name and symbol.<ref>{{Cite web |title=New names, new symbols: EC allots 'football player' symbol to Mamata faction, rebels get 'envelope' |url=https://www.theweek.in/news/india/2026/09/18/new-names-new-symbols-ec-allots-football-player-symbol-to-mamata-faction-rebels-get-envelope.html |access-date=2026-09-18 |website=@theweek |language=en}}</ref>
