Vladimir Ivanovich Kozlov is a Kazakh journalist and politician who has been a leader of the democratic opposition in Kazakhstan and a candidate for his country's presidency. In 2012, he was the defendant in what Deutsche Welle described as "the first political trial in Kazakhstan." The US charged Kazakhstan with using its criminal-justice system "to silence a leading opposition voice." Kozlov, who was found guilty and served a prison sentence, has been designated by Amnesty International as a "prisoner of conscience." He was released in 2016.
