Suvendu Adhikari will be sworn in as the new chief minister of West Bengal on May 9, 2026 [1].

The transition marks a historic political shift in the state, as the Bharatiya Janata Party (BJP) replaces the 15-year administration of Mamata Banerjee and the Trinamool Congress (TMC) [2].

The ceremony is scheduled to take place at 11 a.m. [3] at the state assembly premises in Kolkata [4]. Preparations at the assembly have already begun, with officials removing nameplates of outgoing ministers and installing new signages for the incoming cabinet [4].

Samik Bhattacharya, the state BJP chief, confirmed the timing of the event. "The oath-taking ceremony of the new chief minister of West Bengal will take place on May 9," Bhattacharya said [5].

The appointment follows a period of intense government formation and post-election activity. While some initial reports indicated that Union Home Minister Amit Shah was meeting with newly elected MLAs to finalize the leadership choice, later reports confirmed Adhikari as the designated head of the government [6].

Adhikari's ascension to the chief ministership represents the first time the BJP has held the top executive office in West Bengal. The party's victory in the assembly elections allows them to implement their platform after more than a decade of TMC dominance [2].

The shift from the TMC to the BJP ends a long era of regional dominance by Mamata Banerjee. This transition represents a significant consolidation of power for the BJP in eastern India, potentially altering the administrative and political landscape of West Bengal after 15 years of stable, single-party rule.
