May 2026 attack

On 30 May 2026, a mob attacked TMC leader Abhishek Banerjee in Sonarpur in South 24 Parganas district. This incidence resulted in big political controversy, with Mamata Banerjee alleging BJP for this incidence, and BJP denying having any linkage to the given incidence.

On the next day, on 31 May 2026, Kalyan Banerjee was reportedly attacked in Chanditala, West Bengal in his own constituency. Banerjee was hit on his head with policemen standing there.

Two incidences of high profile attacks on two senior leaders of TMC led to huge political polarization in West Bengal, with the Indian National Developmental Inclusive Alliance (INDIA alliance), also coming in open support of Mamata Banerjee on these issues.

Meanwhile Mamata has announced public protest on 02 June against the attacks on Abhishek Banerjee and Kalyan Banerjee in rapid succession.

2026 MPs Rebellion Following the 2026 Assembly Elections, 20 out of the 28 Members of Parliament from Trinamool Congress decided to leave Mamata Banerjee and the Trinamool Congress. They formed a new group and decided to merge with a relatively little known National Party, the Nationalist Citizen Party of India and presented a representation in this regards to Lok Sabha Speaker Om Birla on 14 June 2026.

After this major split in the Trinamool Congress, only 8 Lok Sabha MPs remained loyal to Mamata Banerjee. The loyalist MPs included Abhishek Banerjee, Mahua Moitra, Saugata Roy, Kalyan Banerjee, Kirti Azad, Pratima Mondal and Sajda Ahmed.

The event is still unfolding.
