[1][2] He previously served as Secretary of the National Security and Defence Council of Ukraine, appointed after the Euromaidan protests in the 2014 Ukrainian revolution,[8] until his resignation on August 7, 2014.

[16] In February 2010 Parubiy asked the European Parliament to reconsider its negative reaction to former Ukrainian President Victor Yushchenko's decision to award Stepan Bandera, the leader of the Organization of Ukrainian Nationalists, the title of Hero of Ukraine.

[22] As Secretary of the National Security and Defense Council, Parubiy supported the anti–terrorist operation against pro-Russian separatists in eastern Ukraine.

He declined to say why, stating "I believe it is unacceptable to comment on my resignation in a time of war", and he would "continue to assist the front, primarily volunteer battalions".

After the resignation of Volodymyr Groysman, on 14 April 2016 he was elected as Chairman of the Verkhovna Rada (the Ukrainian equivalent of legislative speaker of parliament).

[2] Despite having left far-right politics in 2004[28] Parubiy has frequently been the target of disinformation and fake news by pro-Russian media, who routinely refer to him as a "Nazi", especially after the Revolution of Dignity.

For example, after the Constitutional Court of Ukraine declared the Law on National Referendums unconstitutional, Parubiy cautioned against the use of referendums to manipulate the population, pointing out that Adolf Hitler also used referendums in Nazi Germany to accomplish his goals;[29] Russian media (such as RIA Novosti, RT, Zvezda, NTV, Sputnik and others), Ukrainian pro-Russian media (112 Ukraine, NewsOne, Strana.ua, KP and others) and Ukrainian pro-Russian politicians (such as Vadim Rabinovich and Viktor Medvedchuk) distorted Parubyi's phrase, stating that Parubiy had openly praised Hitler.
