For some time, the Russian Duma has been dominated by United Russia, the 'party of power' that is faithful to Putin. Its current majority of 67.56% enables it to change the constitution without assistance. Acting in concert with the Fair Russia Party, the result of a merger between the Rodina and Shisn parties in 2006, United Russia largely supports the policies of the Kremlin, whereas alternative opinions are only intermittently heard in the Duma. United Russia controls legislation, acting as an instrument of the national government and particularly the Russian president.
