In December 2003, Belykh was a parliamentary candidate for the Union of Right Forces, which failed to pass the nationwide 5% threshold required for entering the State Duma.

On May 28, 2005, Belykh was elected leader of the Union of Right Forces, a leading opposition party, succeeding Boris Nemtsov.

As a result of the agreement between Belykh and Grigory Yavlinsky reached in October 2005, the Union of Right Forces and Yabloko formed a coalition, Yabloko-United Democrats, to contest the Moscow City Duma elections on December 4, 2005.

In September 2008 Belykh announced that he had resigned from his position and left the Union of Right Forces in connection with its likely merger with a couple of pro-Kremlin parties.
