Amid the protests following the murder of Boris Nemtsov, two Russian opposition parties are joining forces to counter the Kremlin, who many believe bears responsibility for the dissident’s death.<br /><br /> The political party Nemtsov formed is to run for election with the party of another opposition activist, Alexei Navalny – although its chairman said the move was not a merger.<br /><br /> Both parties called for a common platform to reject lies, corruption and aggression and build a democratic state.<br /><br /> A third small party is also set to join.<br /><br /> Navalny and other critics of the Kremlin have been prosecuted and convicted of charges they denounce as political.<br /><br /> Previous attempts by opposition groups to unite have failed as they have agreed on little other than opposition to Putin.<br /><br /> The new alliance says it will begin by running in regional elections ahead of next year’s parliamentary vote.
