All India Trinamool Congress

AITC party symbol

All India Trinamool Congress, earlier West Bengal Trinamool Congress, (WBTC), was a political party in India. The party was led by Mamta Banerjee and was a splinter-group of the Indian National Congress. In the Lok Sabha elections in 1999 AITC got 2,6% of votes and eight seats. Ahead of the 2004 Lok Sabha elections AITC merged with P.A. Sangma's break-away fraction of the Nationalist Congress Party. The new party is called Nationalist Trinamool Congress.

Prior to the merger the students wing of the party was known as Trinamool Chhatra Parishad, the teachers wing Nationalist Democratic Teachers’ Association and the trade union wing was called Indian National Trinamool Trade Union Congress. What these organizations are named after the merger with Sangma is unclear.
