In the 2003 parliamentary elections the SPS, according to official results, received 4% of the vote and failed to cross the 5% threshold necessary for parliamentary representation. A number of SPS candidates came second in single-mandate electoral districts the party had previously held, such as Irina Khakamada in St. Petersburg, Vladimir V. Kara-Murza in Moscow, or Boris Nadezhdin in the Moscow region. Despite allegations of fraud, Boris Nemtsov accepted responsibility for the election defeat and resigned as SPS leader in January 2004. On 28 May 2005 Nikita Belykh was elected as the new leader of the party.
