Democratic Front is the name of the former governing coalition in the Indian state of Maharashtra.
Its core constituents are Nationalist Congress Party and Indian National Congress. This alliance was created post 1999 Maharashtra Assembly Poll results as Congress and NCP contested against each other without a pre-poll alliance but came together to stake claim to form the government.
This alliance ended on 25 September 2014 when Nationalist Congress Party officially announced it in press conference and removed support to State Government.
