Russian anti-corruption campaigner and opposition blogger Alexei Navalny on Thursday slammed President Vladimir Putin’s increasing crackdown on dissenting voices with a law against “undesirable NGOs.” The legal measure follows 2012 legislation allowing the branding of any group that receives foreign funding as a “foreign agent” and is part of a Kremlin-fueled campaign that associates its critics with a so-called “fifth column” of national traitors.
