The Trinamool Congress (TMC) is confronting one of the most serious internal crises in its recent history as the alleged forged signature scandal, widely referred to as “Signgate,” intensifies across West Bengal. Emerging just weeks after the party’s defeat in the 2026 Assembly elections, the controversy has triggered a criminal investigation, exposed internal dissent, led to the expulsion of two legislators, and raised uncomfortable questions about decision-making within the party leadership.
At the centre of the dispute are documents submitted to the West Bengal Assembly concerning the appointment of key opposition positions, including the Leader of the Opposition. Allegations that signatures of multiple TMC legislators were used without their knowledge have transformed what initially appeared to be a procedural dispute into a major political challenge for the party as it attempts to rebuild after losing power.
The scandal has also brought renewed scrutiny to the party’s internal functioning at a time when it is struggling to maintain unity following the end of its 15-year rule in West Bengal.

How the Signature Controversy Unfolded
The row stems from a resolution reportedly submitted to the Assembly Speaker’s office to formalize appointments of opposition leaders within the legislature. According to allegations raised by party MLAs Ritabrata Banerjee and Sandipan Saha, the resolution contained signatures and endorsements that had not been properly authorized.
The two legislators formally approached the Speaker, claiming that no valid resolution had been adopted in the manner described in the submitted documents. Their complaint prompted administrative action and eventually led to a police case, which was later transferred to the Criminal Investigation Department (CID) for a detailed probe.
Investigators have since begun collecting statements, conducting signature verification exercises, and examining the authenticity of signatures attached to the disputed documents.
The controversy escalated dramatically after state authorities publicly disclosed the identities of the complainants and revealed that multiple legislators had reportedly informed investigators that the signatures attributed to them did not belong to them.
Expulsion of Two MLAs Intensifies Internal Conflict
In a move that underscored the seriousness of the crisis, the TMC expelled Ritabrata Banerjee and Sandipan Saha, accusing them of engaging in anti-party activities.
The decision immediately exposed divisions within the party. Both legislators defended their actions, insisting they had acted to highlight procedural irregularities rather than undermine the organisation.
Saha argued that elected representatives had no knowledge that attendance records or related documents would later be used for a formal resolution submitted to the Assembly. Banerjee similarly maintained that raising concerns about alleged irregularities was necessary and in the interest of transparency.
The expulsions have become a focal point of the controversy because they transformed a dispute over documentation into a broader debate about internal accountability and dissent within the party.

Investigation Moves Closer to Senior Leadership
The political stakes increased further as the investigation expanded beyond rank-and-file legislators.
Senior party figures have come under scrutiny, including leaders involved in preparing and submitting the disputed documents. The CID has continued gathering evidence and questioning individuals connected to the process.
The probe seeks to establish whether signatures were intentionally forged, whether procedural rules were violated, and who may bear responsibility if wrongdoing is confirmed.
The investigation’s outcome could have significant political implications because the disputed documents were linked to the party’s official functioning inside the Assembly following its transition to the opposition benches.
Expert Analysis / What This Means
The Signgate controversy is far more damaging than a routine administrative dispute because it strikes at the heart of organisational discipline within a party that has traditionally projected strong central control.
For TMC, the timing could hardly be worse. The party is already attempting to recover from a historic electoral setback that ended its dominance in West Bengal politics. Allegations of forged signatures risk reinforcing public perceptions of internal disorder at a moment when rebuilding credibility is critical.
The dispute also highlights the challenges opposition parties face after losing power. Internal disagreements that might once have remained hidden often become more visible when electoral authority weakens.
The investigation could influence future leadership dynamics within TMC, particularly if additional legislators publicly challenge the party’s handling of internal decisions.
From a governance perspective, the case raises broader concerns about procedural transparency in legislative processes and the handling of official Assembly documentation.
If the probe uncovers evidence of deliberate misconduct, the controversy may extend beyond political embarrassment and carry legal consequences for those involved.
Why This Matters
The significance of the scandal extends beyond the immediate allegations.
TMC’s defeat in the 2026 Assembly elections marked a turning point in West Bengal politics. After governing the state since 2011, the party now faces the challenge of operating as the principal opposition force.
Political analysts often view the post-defeat period as a test of a party’s institutional strength. Internal cohesion, leadership credibility, and organisational discipline become critical factors in determining whether a party can successfully stage a comeback.
The forged-signature controversy has therefore become a broader referendum on the party’s ability to maintain unity during a period of transition.
Timeline of Events
- TMC submits documents related to appointments of opposition leaders in the Assembly.
- Questions emerge regarding the authenticity of signatures included in the resolution.
- MLAs Ritabrata Banerjee and Sandipan Saha file a complaint with the Assembly Speaker.
- An FIR is registered and the case is subsequently transferred to the CID.
- Investigators begin signature verification and collect statements from legislators.
- Reports emerge that multiple MLAs dispute signatures attributed to them.
- TMC expels Banerjee and Saha for alleged anti-party activities.
- The investigation expands, drawing attention to senior party leaders and internal decision-making processes.
What Happens Next?
The CID investigation is expected to continue over the coming weeks as officials examine documentary evidence and gather testimonies from legislators and party functionaries.
Investigators will seek to determine whether criminal offences occurred, whether signatures were fabricated, and whether any official procedures were bypassed.
Politically, however, the fallout may continue regardless of the legal outcome. The controversy has already exposed fault lines within TMC and intensified scrutiny of the party’s leadership structure.
As West Bengal’s political landscape adjusts to a new balance of power, the Signgate scandal is likely to remain a defining challenge for TMC’s efforts to regroup, rebuild confidence among supporters, and establish itself as a cohesive opposition force.
