In addition, Vladimir Putin signed a law which replaced the direct election of the heads of the federal subjects of Russia with a system whereby they are proposed by the President of Russia and approved or disapproved by the elected legislative bodies of the federal subjects. The election system for the Russian parliament was also repeatedly amended, eliminating the election of State Duma members by single-mandate districts. The Kremlin consolidated its control over the Russian media and increasingly attacked the non-governmental organizations (especially those foreign-founded).
