Uddhav Thackeray’s Shiv Sena (UBT) faces a potential parliamentary split as six of its nine Lok Sabha members may form a breakaway group to align with the Eknath Shinde-led Shiv Sena. This development follows a similar crisis within the Trinamool Congress (TMC), where 20 MPs have proposed merging with the Nationalist Citizens Party of India (NCPI). These shifts could alter Lok Sabha arithmetic as the ruling National Democratic Alliance (NDA) seeks support for the proposed delimitation bill, according to reports citing party insiders and parliamentary sources.
What is the status of the Shiv Sena (UBT) split?
The Shiv Sena (UBT) is facing a rebellion known as “Operation Tiger,” with insiders claiming six MPs are preparing to submit a letter to Lok Sabha Speaker Om Birla to merge with the rival Sena unit. According to reports, the MPs identified in this potential breakaway are Sanjay Jadhav, Bhausaheb Wakchaure, Sanjay Deshmukh, Nagesh Patil Ashtikar, Omraje Nimbalkar, and Sanjay Patil. However, this list remains unverified. Shiv Sena (UBT) MP Sanjay Raut has stated that the party has issued a whip for a parliamentary meeting on Thursday, warning of legal action against any member who fails to attend.
Did You Know? Under the Tenth Schedule, a political party must ensure a two-thirds majority of its parliamentary unit to avoid disqualification during a merger; for the Shiv Sena (UBT), this requires at least six of its nine members to successfully form a separate group.
How does the TMC crisis impact national politics?
The Trinamool Congress (TMC) is currently managing a rebellion involving 20 Lok Sabha MPs who wrote to Speaker Om Birla proposing a merger with the NCPI. If recognized, this shift would increase the NDA’s strength in the Lok Sabha from 294 to 314 seats, though it would remain 46 seats short of the two-thirds majority threshold. Speaker Birla has delayed formal approval of the merger, opting to hear the TMC leadership first, according to the Lok Sabha Secretariat. TMC floor leader Abhishek Banerjee has been asked to meet the Speaker later this week to present the party’s formal opposition to the move.

What happens next in the parliamentary proceedings?
The immediate political trajectory depends on the Speaker’s interpretation of the Tenth Schedule. While rebel factions in both parties cite a merger, TMC floor leader Abhishek Banerjee has argued that a “split is no longer available” under current rules, characterizing the TMC as an indivisible entity. If the Speaker rejects the merger claims, the rebel MPs would face disqualification for violating party whips. Conversely, if the mergers are recognized, the NDA would move closer to the numbers required to advance the proposed delimitation bill, although it would still fall short of a two-thirds majority in both houses of Parliament.
Expert Insight: The Stakes of Party Defection
Expert Insight: These events underscore a recurring tension in Indian parliamentary democracy: the balance between individual lawmaker agency and the Tenth Schedule’s anti-defection provisions. The focus on the Speaker’s office highlights that the final arbiter of these legislative shifts is not the electorate, but the procedural recognition of party unity. For the NDA, these defections represent a strategic opportunity to consolidate numbers, yet the legal threshold of a two-thirds majority remains a significant barrier to passing major constitutional amendments.
