In the 2004 Andhra Pradesh Assembly election, the Congress had swept the state, winning 185 of the 294 seats in the Assembly.
The Congress' pre-poll alliance partners Left Front and TRS also did well winning 15 and 26 seats respectively, taking the UPA tally to 226. As the leader of the Congress Legislature Party, Y.S. Rajasekhara Reddy was invited to form the Government by Governor S.S. Barnala.
