The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body in the United Kingdom, British Crown dependencies and British overseas territories. It is located in Westminster, London. Parliament alone possesses legislative supremacy and thereby ultimate power over all other political bodies in the UK and its territories. At its head is the Sovereign, Queen Elizabeth II.

The parliament is bicameral, with an upper house, the House of Lords, and a lower house, the House of Commons. The Queen is the third component of the legislature. The House of Lords includes two different types of members: the Lords Spiritual (the senior bishops of the Church of England) and the Lords Temporal (members of the Peerage) whose members are not elected by the population at large, but are appointed by the Sovereign on advice of the Prime Minister. Prior to the opening of the Supreme Court in October 2009 the House of Lords also performed a judicial role through the Law Lords.

George Galloway (born 16 August 1954) is a British politician, author, journalist, and broadcaster, and the Respect Member of Parliament (MP) for Bradford West. He was previously an MP for the Labour Party, for Glasgow Hillhead and then its successor constituency Glasgow Kelvin from 1987 until 2005. He was expelled from the Labour Party in October 2003 because of his strident public opposition to the Iraq War. He subsequently became a founding member of the left-wing Respect Party, and was elected as the MP for Bethnal Green and Bow in 2005. In 2010, Galloway unsuccessfully contested the seat of Poplar and Limehouse, and in 2011 he unsuccessfully contested the Glasgow list for the Scottish Parliament, before being elected as an MP in the Bradford West by-election, 2012.

Galloway is well known for his campaigns in support of the Palestinians in the Israeli–Palestinian conflict. In the late-1980s Hansard records him delivering a ferocious assault on the Ba'ath regime, and Galloway opposed Saddam's regime until the United States-led Gulf War in 1991. Galloway is known for a visit to Iraq where he met Saddam Hussein, and delivered a speech, which ended in English with the statement "Sir, I salute your courage, your strength, your indefatigability." He has always stated that he was addressing the Iraqi people in the speech. Galloway testified to the United States Senate in 2005 over alleged illicit payments from the United Nations' Oil for Food Programme.

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.
