TMC MP Kakoli Ghosh Dastidar and 19 other MPs are set to support the NDA, marking a significant internal crisis for Mamata Banerjee's party and threatening opposition unity post-election defeat.

Key points

Kakoli Ghosh Dastidar, a four-term TMC MP, announced her faction's support for the NDA, citing dissatisfaction with the party's governance and development record in West Bengal.

The rebel group claims support from 19 out of 28 TMC MPs, aiming to avoid anti-defection proceedings by meeting the two-thirds threshold required under the 10th Schedule of the Constitution.

This development follows 58 TMC MLAs supporting rebel leader Ritabrata Banerjee for the Leader of Opposition position in the West Bengal assembly, indicating deep internal strife.

[GS2-Polity] The crisis highlights the challenges of maintaining party discipline under the Anti-Defection Law, which allows splits only if two-thirds of the party's members defect.

The rebels met with Bengal CM Suvendu Adhikari and Union Minister Bhupender Yadav, signaling BJP's strategic exploitation of TMC's internal weaknesses.

[GS3-Security] The political instability in West Bengal could impact governance and law and order, with rebels alleging 'misgovernance' and 'lawlessness' under TMC rule.

The crisis weakens the INDIA bloc, as TMC's fragmentation reduces opposition unity ahead of crucial national elections.

Mamata Banerjee faces dual challenges: managing urban political structures after resignations of key mayors and retaining control over the party's parliamentary and legislative wings.

Way Forward: TMC needs internal democratic reforms to address grievances, while the Election Commission should enforce stricter anti-defection measures to prevent opportunistic defections.

Key terms

Two-thirds rule

Under the 10th Schedule, a split is recognized only if at least two-thirds of a party's legislators defect together. This UPSC-relevant concept tests understanding of constitutional safeguards against political instability, often appearing in GS2 questions on defection and party systems.

10th Schedule of the Constitution

The 10th Schedule, also known as the Anti-Defection Law, was added by the 52nd Amendment Act, 1985. It disqualifies MPs/MLAs who defect from their party or violate party whip, with exceptions for splits (if 2/3 of party members defect) or mergers. This is crucial for UPSC as it tests understanding of constitutional mechanisms to ensure political stability.

INDIA bloc

The Indian National Developmental Inclusive Alliance (INDIA) is a coalition of opposition parties formed to contest the 2024 general elections against the NDA. Its relevance lies in understanding India's evolving federal polity and coalition dynamics, a key topic in GS2 (Polity) and GS2 (Governance).

Leader of Opposition

The Leader of Opposition is a statutory position recognized under the Salary and Allowances of Leaders of Opposition in Parliament Act, 1977. To qualify, a party must have at least 10% of the total seats. This is institutionally significant for UPSC as it relates to parliamentary democracy and checks-and-balances in GS2 (Polity).
