Viktor Fedorovych Yanukovych (Ukrainian:  Ві́ктор Фе́дорович Януко́вич (help·info), Russian: Виктор Фёдорович Янукович; born July 9, 1950) is a Ukrainian politician who has been the President of Ukraine since February 2010.

Yanukovych served as the Governor of Donetsk Oblast from 1997 to 2002. Subsequently he was Prime Minister of Ukraine from November 21, 2002, to December 31, 2004, under President Leonid Kuchma, and he was an unsuccessful candidate in the 2004 presidential election, ultimately losing to Viktor Yushchenko. Yanukovych continued to lead his party, the Party of Regions, after the 2004 election, and he served as Prime Minister for a second time from August 4, 2006, to December 18, 2007 under President Yushchenko. On March 3, 2010, Yanukovych transferred the leadership of the party to Mykola Azarov.

Yanukovych won most votes in the first round of the January 2010 presidential election, and faced Yulia Tymoshenko in the second round of the election. Yanukovych won the second round of the election with 48.95% of the vote against Tymoshenko's 45.47%. He is the first directly elected president in Ukraine's history to win with less than 50% of the vote.

Vladimir Vladimirovich Putin (Russian: Влади́мир Влади́мирович Пу́тин; IPA: [vɫɐˈdʲimʲɪr vɫɐˈdʲimʲɪrəvʲɪtɕ ˈputʲɪn] ( listen); born 7 October 1952) is a Russian politician who has been the President of Russia since 7 May 2012. Putin previously served as President from 2000 to 2008 and as Prime Minister of Russia from 1999 to 2000, and again from 2008 to 2012. Putin also serves as chairman of United Russia and Chairman of the Council of Ministers of the Union of Russia and Belarus. He became acting President on 31 December 1999, when president Boris Yeltsin resigned in a surprising move. Putin won the 2000 presidential election; in 2004 he was re-elected for a second term lasting until 7 May 2008.

Because of constitutionally mandated term limits, Putin was ineligible to run for a third consecutive presidential term. After his successor Dmitry Medvedev won the 2008 presidential election, Putin was nominated by Medvedev to be Russia's Prime Minister; Putin took office on 8 May 2008 and a period of so-called "tandemocracy" followed. In September 2011, Putin and Medvedev agreed he should seek a third, non-consecutive term in the 2012 presidential election, which he won in the first round on 4 March 2012.
