Doğu Perinçek (June 17th, 1942 - ) is a Turkish politician and lawyer who has been chairman of the left-wing nationalist Patriotic Party (Turkish) Vatan Partisi
In 2007, a ruling by a Swiss court made him the first person to receive a criminal conviction for denial of the Armenian genocide. He is a known Genocide denier. The case was ultimately appealed to the Grand Chamber of the European Court of Human Rights, which in a 15 October 2015 judgment did not dispute the fact of the Armenian genocide but ruled in favour of Perinçek on grounds of free speech.
In August 2013 he was sentenced to aggravated life imprisonment as part of Turkey's Ergenekon trials, but he was released in 2014.
