In 2000, Gorbachev helped form the Russian United Social Democratic Party. In June 2002 he participated in a meeting with Putin, who praised the venture, suggesting that a center-left party could be good for Russia and that he would be open to working with it. In 2003, Gorbachev's party merged with the Social Democratic Party to form the Social Democratic Party of Russia, which faced much internal division and failed to gain traction with voters. Gorbachev resigned as party leader in May 2004 following a disagreement with the party's chairman over the direction taken in the 2003 election campaign. The party was later banned in 2007 by the Supreme Court of the Russian Federation due to its failure to establish local offices with at least 500 members in the majority of Russian regions, which is required by Russian law for a political organization to be listed as a party. Later that year, Gorbachev founded a new movement, the Union of Social Democrats. Stating that it would not contest the forthcoming elections, Gorbachev declared: "We are fighting for power, but only for power over people's minds".
