Moscow - Three Kremlin-friendly opposition parties merged Sunday into a new liberal party called Just Cause.
The parties, who failed to win seats in the Russian parliament or Duma in elections in 2007, joined forces with an eye on the next vote in 2011.
At the party's inaugural congress on Sunday, the initiators said the move had been discussed with the Kremlin, according to Moscow radio broadcaster Echo Moskvy.
The party had been formed with the help of the Kremlin, but not by the Russian government, said Leonid Gosman, deputy chairman of the Union of Just Forces (SPS).
The SPS and its two allies, the Democratic Party and the Citizens' Force, disbanded to to form the new union.
