Indian security forces deployed outside the Nationalist Citizens Party of India (NCPI) office in Howrah on Monday following a major political merger [1].

This shift in allegiance significantly alters the parliamentary landscape in West Bengal. By pledging support to the BJP-led National Democratic Alliance (NDA), the rebel faction weakens the Trinamool Congress (TMC) and strengthens the ruling coalition's position in the Lok Sabha.

Police and paramilitary units were stationed at the NCPI office in Howrah, Kolkata, to maintain order after the announcement [1]. The deployment was prompted by security concerns surrounding the high-profile nature of the political move [2].

The group consists of 20 rebel TMC Lok Sabha MPs who have officially merged with the NCPI [1]. This collective move represents a substantial defection from the TMC, as the MPs have now pledged their support to the NDA [1].

Authorities increased the security presence to prevent potential clashes between opposing political supporters in the Howrah area [2]. The presence of security forces remained a priority as the NCPI integrated the new members into its party structure [1].

Local officials monitored the situation as the rebel MPs finalized the merger process on June 15, 2026 [2]. The strategic alignment with the NCPI allows these legislators to maintain their seats while shifting their legislative loyalty to the NDA coalition [1].

Twenty rebel TMC Lok Sabha MPs merged with the NCPI and pledged support to the BJP-led NDA.

The merger of 20 TMC MPs into the NCPI creates a significant power shift in West Bengal's representation within the Indian Parliament. By aligning with the NDA, these legislators provide the BJP-led coalition with additional leverage, while simultaneously creating a crisis of stability for the TMC's regional influence.
