The immediate backdrop is the long-running political rivalry in West Bengal that has centered on Nandigram since 2020–21, when a high-profile defection and the 2021 assembly contest transformed the seat into a symbol of the broader struggle between Mamata Banerjee’s Trinamool Congress and the Bharatiya Janata Party.
That period saw Suvendu Adhikari leave the Trinamool Congress in December 2020 and join the BJP, setting up a direct electoral showdown in the Nandigram constituency during the April–May 2021 West Bengal assembly elections.
Mamata Banerjee announced she will back the Congress candidate in the Nandigram Assembly bypoll after Sanchita Pradhan (Dey) withdrew her nomination, a development the Banerjee-led All India Trinamool Congress described publicly on September 18, 2026.
The move follows Pradhan's meeting with Suvendu Adhikari and came only hours after the Election Commission assigned the Banerjee-led faction a new party name and symbol for the October 6 bypolls (per thehindu.com).
The immediate consequence is political: Pradhan's exit leaves the Mamata All India Trinamool Congress without a candidate in a high-profile seat that has been politically contested between Mamata Banerjee and opponents.
Banerjee framed her decision as tactical support for Congress in the constituency, while the sequence of events — the EC action followed by Pradhan's meeting with Suvendu Adhikari and then her withdrawal — fuels questions about internal cohesion within the Banerjee-led faction and possible individual calculations by Pradhan (per thehindu.com).
Pradhan's meeting with Suvendu Adhikari is documented in the reporting as preceding her withdrawal, but the source does not quote Pradhan, Adhikari or other principals explaining motives; nor does it provide statements from the Congress candidate about receiving Banerjee's backing.
The Election Commission's assignment of a new party name and symbol for the October 6 bypolls is presented as a proximate administrative action that coincided with the political fallout (per thehindu.com).
What is clear from the reporting is a rapid realignment in Nandigram: one AITC-linked candidate has stepped aside, the AITC leader has offered explicit support to Congress, and the seat will be contested on October 6 under the new party identifier assigned to Banerjee's faction.
The article limits its claims to these documented steps and does not assert causation beyond the observed sequence of EC action, the meeting with Suvendu Adhikari, and Pradhan's withdrawal (per thehindu.com).
Whether Sanchita Pradhan (Dey) files any public statement explaining her withdrawal by September 20, 2026 (per thehindu.com sequence). 2) Whether the Congress candidate in Nandigram formally accepts and publicizes Mamata Banerjee's support before the October 6 bypolls (per thehindu.com). 3) Whether the Election Commission's new party name and symbol for the Banerjee-led faction is used in campaign materials in Nandigram between now and October 6 (per thehindu.com).
