2026 Rebellion

In June 2026, almost immediately after the massive Trinamool Congress defeat, around 20 MPs of AITC allegedly declared rebellion from their party, and presented their written wish to join Bhartiya Janata Party. This group was led by Kakoli Ghosh.

Later, on 14 June, 20 MPs, including Bandyopadhyay, signed a formal letter declaring their split from Trinamool Congress as to merge with the Nationalist Citizens Party of India (NCPI), having a national party status granted by the Election Commission of India. They formally submitted the letter to Lok Sabha Speaker Om Birla.

The total strength of TMC in Lok Sabha had been 28, so that a number of 20 MPs made it eligible for splitting from the party, as per the Indian Defection laws, so as to escape the anti-defection disqualification.
