Andriy Klyuyev

Andriy Petrovych Klyuyev (Ukrainian: Андрій Петрович Клюєв, Russian: Андрей Петрович Клюев, born 12 August 1964), also spelled as Andrii Kliuiev, is a Ukrainian businessman and politician, who was ranked as 7th "Most influential person in Ukraine" in 2011 by Korrespondent.

Under the Presidency of former President Viktor Yanukovych, Klyuyev served as First Vice Prime Minister from 2010 to 2012, and then he served as Secretary of the National Security and Defense Council of Ukraine under Yanukovych for two years. From 23 January to 23 February 2014, amidst the escalation of Euromaidan into the Revolution of Dignity, he worked as the head of the Presidential Administration of Ukraine. His brother Serhiy Klyuyev is also a politician and businessman.

In June 2009, the Klyuyev brothers were ranked 48th in the Korrespondent's list of Top 50 richest Ukrainians with the estimated wealth of US$227 million. As of 2011, the Klyuyevs own a mansion on a 27-hectare (67-acre) site near Vienna at Tulbing, Groissaustraße 12, and a large 17-hectare (42-acre) site at Rudyky (Рудики). He was last seen publicly with Viktor Yanukovych in Balaklava, Ukraine in early 2014. Since then, he has made occasional appearances on Russian television shows, confirming he is alive. Regarding his disappearance from Kyiv since the Revolution of Dignity overthrew President Viktor Yanukovych, Klyuyev has claimed that he moved to Donetsk in 2014, which he considers Ukrainian territory (although Donetsk is no longer controlled by Ukrainian authorities since the start of the Russo-Ukrainian War in 2014). In 2019, the Security Service of Ukraine stated that Klyuyev was living in hiding in Russia, and in 2022 a British Foreign, Commonwealth and Development Office report alleged that Klyuyev, along with three other former Ukrainian government officials who served under Yanukovych, was allegedly working with the Russian intelligence services to "subvert Ukraine".
