The Prime Minister of Poland (Polish: Prezes Rady Ministrów) heads the Polish Council of Ministers (the Cabinet) and directs their work, supervises territorial self-government within the guidelines and in ways described in the Constitution and other legislation, and acts as the superior for all government administration workers (heading the public service corps).

The full name of the office is the "Chairman of the Council of Ministers" (in Polish Prezes Rady Ministrów), but this version is very rarely used in English. In Polish the office is usually called Premier. Until 1922, the Prime Minister was called "President of the Ministers" (Prezydent Ministrów).

At the same time, the Prime Minister may fulfil the duties of a department head or a committee chairman. The Prime Minister may also be a Representative at the Sejm of the Republic of Poland. He cannot, however, hold the post of the President of the RP or any other high state office such as the Chairman of the NIK (Supreme Chamber of Control), Chairman of the NBP (National Bank of Poland) or a Civil Rights Spokesman (Ombudsman).

A prime minister is the most senior minister of cabinet in the executive branch of government in a parliamentary system. In many systems, the prime minister selects and may dismiss other members of the cabinet, and allocates posts to members within the government. In most systems, the prime minister is the presiding member and chairman of the cabinet. In a minority of systems, notably in semi-presidential systems of government, a prime minister is the official who is appointed to manage the civil service and execute the directives of the head of state.

In parliamentary systems fashioned after the Westminster system, the prime minister is the presiding and actual head of the government and head of the executive branch. In such systems, the head of state or the head of state's official representative (i.e. the monarch, president, or governor-general) usually holds a largely ceremonial position, although often with reserve powers.

The prime minister is often, but not always, a member of parliament and is expected with other ministers to ensure the passage of bills through the legislature. In some monarchies the monarch may also exercise executive powers (known as the royal prerogative) which are constitutionally vested in the crown and may be exercised without the approval of parliament.

Donald Franciszek Tusk [ˈdɔnalt franˈt​͡ɕiʂɛk ˈtusk] ( listen) (born 22 April 1957) is a Polish politician who has been Prime Minister of Poland since 2007. He was a co-founder and is chairman of the Civic Platform (Platforma Obywatelska) party.

Tusk was officially designated as Prime Minister on 9 November 2007 and took office on 16 November. His cabinet won a vote of confidence in the Sejm on 24 November 2007. He is currently the longest serving prime minister of the Third Republic of Poland. In October 2011, Tusk's Civic Platform won a plurality of seats in the Polish parliamentary election, meaning that Tusk became the first Prime Minister to be re-elected since the fall of communism in Poland.

Tusk began his public career as an activist in his home town of Gdansk, supporting Solidarity and organizing his fellow university students. With the exception of one four-year stretch, Tusk has served in the Third Republic parliament almost continuously since its first elections in 1991. He was Vice Marshal (deputy speaker) of the Senate from 1997 to 2001 and Vice Marshal of the Sejm from 2001 to 2005. He also served as Leader of the Opposition from 2003 to 2007.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
