Trinamool Congress

The All India Trinamool Congress (AITC) is an Indian political party with significant influence in West Bengal. It was established by Mamata Banerjee on January 1, 1998, as a breakaway faction from the Indian National Congress and swiftly gained prominence in West Bengal’s political landscape under her leadership. Currently, the AITC governs West Bengal and ranks as the third-largest party in India by the number of Members of Parliament, following the BJP and the INC.
The party achieved a landmark victory in the 2011 West Bengal Legislative Assembly election, ending the Left Front’s 34-year tenure, which was the longest-serving democratically elected communist government in the world. The AITC has secured a majority in the West Bengal Legislative Assembly three times and has been the ruling party in the state since May 20, 2011. Mamata Banerjee continues to lead the party as its chairperson.

History:
Founding
After over 26 years with the Indian National Congress (INC), Mamata Banerjee left the party and founded the Trinamool Congress (TMC) in 1998. The party’s official election symbol is Jora Ghas Phul (two flowers with grass). In the 1998 Lok Sabha elections, the TMC won seven seats. The following Lok Sabha election in 1999 saw the party increase its tally to eight seats, in alliance with the BJP.
In 2000, the TMC achieved a notable victory by winning the Kolkata Municipal Corporation elections.
Initially, the TMC joined the National Democratic Alliance (NDA) as part of the Vajpayee government and experienced early success, securing seven seats in its debut election. However, the party faced setbacks in the 2004 Lok Sabha elections and the 2006 West Bengal Legislative Assembly elections. These losses led the TMC to exit the NDA. In the 2001 Vidhan Sabha elections, the party won 60 seats in alliance with the INC, emerging as the principal opposition party in West Bengal.
Nandigram Movement
In December 2006, the Haldia Development Authority issued a notice indicating that a large portion of Nandigram would be seized and 70,000 residents evicted to make way for a chemical plant. This announcement triggered a widespread protest against the land acquisition, with the Trinamool Congress (TMC) playing a leading role in the movement. The Bhumi Uchchhed Pratirodh Committee (BUPC), or ‘Committee against Land Evictions,’ was formed to organize the resistance.
On March 14, 2007, the situation escalated when police opened fire on protesters, resulting in the deaths of 14 villagers and many others going missing. Investigations, including a report by the Central Bureau of Investigation, indicated that armed cadres from the Communist Party of India (Marxist) (CPI(M)), along with police, were involved in the violence against the protesters. The brutal crackdown sparked widespread outrage and led to protests from various intellectuals and activists.
The Nandigram events significantly undermined the CPI(M) government and played a crucial role in the TMC’s subsequent electoral success. The movement, led by Socialist Unity Centre of India (Communist) leader Nanda Patra, became a pivotal moment in the political landscape, highlighting the TMC’s role in advocating for marginalized communities and challenging the ruling government’s policies.
Post-Nandigram/Singur Elections
In the 2009 Lok Sabha elections, the Trinamool Congress (TMC) secured 19 seats in West Bengal, forming an alliance with the Congress. Following this success, the TMC joined Manmohan Singh’s government, with Mamata Banerjee appointed as the Minister of Railways.
In the 2010 Kolkata municipal elections, the TMC achieved a significant victory, winning 97 out of 141 seats. The party also gained control of a majority of other municipalities, further consolidating its political influence in West Bengal.
In Government
Mamata Banerjee, as Chief Minister of West Bengal and chairperson of the All India Trinamool Congress (AITC), led the party to a significant victory in the 2011 West Bengal Legislative Assembly elections. The TMC-led alliance, including the Indian National Congress (INC) and the Socialist Unity Centre of India (Communist) (SUCI(C)), won 227 out of 294 seats, ending the Left Front’s 34-year rule. The TMC alone captured 184 seats, enabling it to govern independently. After securing a by-election in Basirhat and with two Congress MLAs joining the TMC, the party’s total increased to 187 seats, while Banerjee moved to the Bhabanipur seat to continue her leadership.
In September 2012, Banerjee withdrew support for the United Progressive Alliance (UPA) over issues like FDI in retail and increases in diesel prices.
The 2014 Lok Sabha elections saw the TMC dominate West Bengal with 34 out of 42 seats, achieving national party status as it garnered 6% of the vote in five states. The Election Commission officially recognized the TMC as a national party on September 2, 2016.
The party secured a supermajority in the 2016 state elections, allowing Banerjee to remain Chief Minister. However, in the 2019 general elections, the TMC, though the largest party in West Bengal, faced substantial losses to the Bharatiya Janata Party (BJP), which made significant gains in the state.
In the 2021 state elections, Banerjee’s party won a decisive victory over the BJP despite defections of key TMC leaders to the BJP. However, Banerjee herself lost in Nandigram to Suvendu Adhikari, a former TMC leader who had defected to the BJP.

Party Symbols and Slogans
The All India Trinamool Congress (TMC) emphasizes its grassroots origins, reflected in both its name and election symbol. “Trinamool,” which means “grassroots” in Bengali, signifies the party’s foundational ethos. The symbol, known as Jora Ghas Phul, features two flowers with grass, representing growth from the ground up. The inclusion of “All India” in the party name signifies a departure from the elitist nature of the Indian National Congress, from which the TMC originated.
Mamata Banerjee coined the slogan “Ma Mati Manush” (Mother, Motherland, and People), which gained prominence during the 2011 West Bengal Assembly elections. The slogan resonated deeply with the electorate and was later immortalized in a Bengali book and a song written by Banerjee.
Another significant slogan is “Joy Bangla” (“Victory to Bengal”), which Mamata Banerjee and the TMC use to foster a sense of regional and cultural identity among Bengalis. This slogan often concludes Banerjee’s political speeches and emphasizes regional pride.
During the 2021 West Bengal Assembly elections, the TMC popularized the slogan “Khela Hobe” (“The Game is On”), which was promoted through a campaign song by Debangshu Bhattacharya, a member of the party’s youth wing. This slogan has become a rallying cry for opposition movements across India, symbolizing resistance against established power structures.Top of Form
Corruption Cases and Convictions
The Trinamool Congress (TMC) has faced several significant corruption allegations and scandals:
- 2014 Saradha Group Financial Scandal: During Mamata Banerjee’s tenure, the Saradha Group financial scandal emerged, involving accusations of money laundering against some TMC ministers. The scandal revealed that Sudipto Sen, a central figure, had purchased one of Banerjee’s paintings for ₹1.8 crore. The Shyamal Sen Commission, established by Banerjee, managed to return ₹185 crore to depositors. Although some leaders from Congress and CPI(M) were also implicated, the Central Bureau of Investigation (CBI) has primarily targeted TMC members in its investigations.
- Rose Valley Financial Scandal: This scandal involved the collapse of a Ponzi scheme run by the Rose Valley Group. Several TMC MPs were accused of money laundering as a result of their involvement with the scheme.
- 2016 Narada Scam: The Narada sting operation, conducted by Tehelka’s Mathew Samuel, exposed high-ranking TMC officials accepting bribes. The publication of the sting just before the 2016 West Bengal Assembly elections added to the controversy surrounding the party.
- 2022 Coal Scam: Rujira Banerjee, wife of TMC’s Abhishek Banerjee, was summoned by the Enforcement Directorate (ED) in connection with a coal theft case. Although she was initially prevented from leaving for the UAE due to a lookout notice, she later appeared before the ED in Kolkata. The Supreme Court of India allowed the ED to question Abhishek Banerjee in Kolkata, but not in Delhi.
- 2022 Cattle Smuggling Case: Anubrata Mondal, a senior TMC leader, was detained by the CBI in connection with a cross-border cattle smuggling case. The investigation has highlighted alleged links between the smuggling racket and various officials.
- 2022 West Bengal School Service Recruitment Scam: This ongoing scam involves irregularities in the recruitment process for school services. The investigation, led by the CBI and ED, began following the arrest of Partha Chatterjee, the then Minister of Education in Banerjee’s cabinet.
Allegations of Extortion: Before coming to power in 2011, TMC leaders were reportedly involved in extortion, demanding a share of funds for new construction projects. The alleged practice continued and expanded once TMC assumed control, leading to the establishment of various local syndicates linked to party leaders
