The United Democratic Front (UDF) is an alliance of political parties in Kerala state, India, created by the prominent Indian National Congress (INC) party leader Shri. K. Karunakaran in the 1970s. Since its formation, the coalition has sustained itself on support from different social, caste and religious groups as a powerful bloc to take on the Communist Party of India (Marxist) (CPI (M)) led Left Democratic Front (LDF). This alliance is led by the INC party in the state of Kerala. In the 2016 Legislative assembly elections UDF just won 47 out of 140 seats and hence lost the power again to Left Democratic Front. Later in 2016 august KC(M) left the alliance.
