Suvendu Adhikari took the oath of office as the first BJP chief minister of West Bengal on May 9, 2026 [1].

The transition marks a seismic shift in the region's political landscape, ending 15 years of rule by the Trinamool Congress [5]. This victory grants the BJP its first-ever leadership of the state government, signaling a realignment of power in eastern India.

Governor RN Ravi administered the oath during a ceremony held in Kolkata [4]. Adhikari was not alone in the proceedings, as five other MLAs were sworn in alongside him [2]. Additionally, five ministers were inducted into the new cabinet to begin the administration's term [3].

The victory follows a contentious electoral battle. Adhikari secured his position with a margin of victory of over 15,000 votes over Mamata Banerjee [4]. The result represents a historic win for the BJP, which has sought to penetrate the West Bengal assembly for several cycles.

Supporters gathered in the capital to witness the transition of power. The ceremony underscores the party's successful effort to dismantle the long-standing dominance of the Trinamool Congress, a feat that has eluded the BJP in previous elections.

The new administration now faces the task of governing a state known for its complex political volatility. With a fresh mandate, Adhikari and his cabinet are expected to implement the party's platform in a state where they previously held no executive authority [1].

Suvendu Adhikari took the oath of office as the first BJP chief minister of West Bengal.

The ascent of Suvendu Adhikari to the chief minister's office represents more than a simple change in leadership; it is the first time the BJP has captured the executive branch in West Bengal. By ending a 15-year tenure of the Trinamool Congress, the BJP has removed a major ideological and political barrier in India's east, potentially altering the national political equilibrium and the implementation of central government policies within the state.
