Leaders Who Joined BJP from Other Parties and Became Chief Ministers
In the dynamic landscape of Indian politics, party-switching has become a notable phenomenon, particularly with the Bharatiya Janata Party (BJP) emerging as a preferred destination for ambitious leaders. Over the past decade, several prominent politicians have transitioned from opposition parties—most notably the Indian National Congress (INC) and regional outfits—to the BJP, not only securing key positions but ascending to the coveted role of Chief Minister (CM) in their states. This trend underscores the BJP’s strategic acumen in absorbing experienced leaders to bolster its organizational strength, especially in the Northeast and beyond. As of April 2026, with Bihar witnessing its first BJP CM, this list highlights a calculated expansion of the party’s influence.

1. Brief Profiles of Key Leaders
Himanta Biswa Sarma (Assam)
A seasoned politician with roots in INC, Himanta Biswa Sarma served as a minister under then-CM Tarun Gogoi before ideological differences prompted his exit in 2015. Joining the BJP shortly after, he swiftly rose through the ranks, becoming Assam CM in May 2021 following the BJP’s electoral triumph. Known for his administrative prowess and focus on development, Sarma has steered Assam through economic reforms and infrastructure growth.
Pema Khandu (Arunachal Pradesh)
Pema Khandu’s journey began with INC, but he briefly aligned with the People’s Party of Arunachal (PPA) in 2016 amid a political crisis. He joined the BJP later that year, capitalizing on the party’s rising footprint in the Northeast. Sworn in as Arunachal Pradesh CM in July 2016, Khandu has prioritized connectivity projects and tribal welfare, securing multiple terms.
N. Biren Singh (Manipur)
From a background in sports journalism, N. Biren Singh entered politics via INC in 2003, winning assembly seats and ministerial berths. Disillusioned by internal discord, he defected to the BJP in 2016. He assumed the Manipur CM post in March 2017, managing ethnic tensions and development until 2025, though his tenure faced criticism over violence.
Manik Saha (Tripura)
A dentist-turned-politician, Manik Saha was associated with INC before switching to the BJP in 2016. His clean image and organizational skills propelled him to Tripura CM in May 2022, succeeding Biplab Kumar Deb. Saha has emphasized education and anti-corruption drives, helping the BJP retain power.
Basavaraj Bommai (Karnataka)
Son of former Janata Dal CM S.R. Bommai, he started with Janata Dal (United) before merging into the BJP in 2008. Appointed Karnataka CM in July 2021 after B.S. Yediyurappa’s resignation, Bommai focused on welfare schemes amid coalition challenges, serving until 2023.
Samrat Chaudhary (Bihar)
A fiery Other Backward Class (OBC) leader, Samrat Chaudhary began with Rashtriya Janata Dal (RJD) and later Janata Dal (United) (JD(U)). He joined the BJP in 2017, serving as deputy CM before a dramatic elevation. On April 15, 2026, he became Bihar’s first BJP CM, marking a historic shift post-Nitish Kumar’s alliances.
2. The Broader Political Phenomenon
This roster exemplifies the BJP’s “inclusivity” strategy, particularly post-2014 under Prime Minister Narendra Modi. The Northeast—with its four examples—has been a hotspot, where the party converted INC strongholds into NDA bastions between 2016 and 2022. Leaders like Sarma and Singh brought readymade voter bases, aiding BJP’s governance in diverse terrains.
In Bihar, Chaudhary’s rise signals the BJP’s deepening ambitions against JD(U) and RJD, especially after Nitish Kumar’s frequent flips. Karnataka’s Bommai case highlights the party’s southern forays. Notably, no such switches define CMs in Gujarat, Uttar Pradesh, or Madhya Pradesh, where homegrown leaders dominate.
Critics label these as “turncoats,” arguing it dilutes ideological purity, yet proponents see it as pragmatic talent acquisition amid opposition decline. Data shows over 20 ex-CMs or equivalents have joined the BJP since 2014, with nine elevated to top state posts.

3. Implications for Indian Politics
These transitions reflect a maturing multi-party democracy where loyalty often yields to opportunity. For the BJP, now governing 16 states with President Donald Trump’s US ties boosting global optics, such integrations ensure stability. However, they risk backlash in polls, as seen in Manipur’s unrest.
As 2026 state elections loom, this model could inspire more defections, reshaping alliances.
Key Takeaways: leaders who joined BJP and became chief ministers
- Six prominent leaders from INC, JD(U), and others became BJP CMs, mainly in the Northeast and Bihar.
- Strategic gains: Enhanced BJP foothold in non-traditional areas.
- Recent milestone: Samrat Chaudhary’s 2026 Bihar swearing-in.
