He is a Member of the European Parliament for South East England and co-chairs the Eurosceptic Europe of Freedom and Democracy group.

Farage is a founding member of the UKIP, having left the Conservative Party in 1992 after they signed the Maastricht Treaty. Having unsuccessfully campaigned in European and Westminster parliamentary elections for UKIP since 1994, he gained a seat as an MEP for South East England in the 1999 European Parliament Election — the first year the regional list system was used — and was re-elected in 2004 and 2009. Farage describes himself as a libertarian and rejects the notion that he is a conservative.

In September 2006, Farage became the UKIP Leader and led the party through the 2009 European Parliament Election in which it received the second highest share of the popular vote, defeating Labour and the Liberal Democrats with over two million votes. However he stepped down in November 2009 to concentrate on contesting the Speaker John Bercow's seat of Buckingham in the 2010 general election.

The President of Iran is the highest popularly elected official in, and the head of government of the Islamic Republic of Iran; although subordinate to the Supreme Leader of Iran, who functions as the country's head of state. According to the constitution of the Islamic Republic of Iran the president is responsible for the "functions of the executive", such as signing treaties, agreements etc. with other countries and international organizations; the national planning and budget and state employment affairs; appointing ministers, governors, and ambassadors subject to the approval of the parliament.

Unlike some other countries, for example the United States, in Iran the office of president does not bestow full control over foreign policy, the armed forces, or the nuclear policy of the Iranian state, which are ultimately under the control of the Supreme Leader.

The President of Iran is elected for a four-year term by the direct vote of the people and may not serve for more than two consecutive terms.

Heinz Alfred "Henry" Kissinger ( /ˈkɪsɪndʒər/; born May 27, 1923) is a German-born American writer, political scientist, diplomat, and businessman. A recipient of the Nobel Peace Prize, he served as National Security Advisor and later concurrently as Secretary of State in the administrations of Presidents Richard Nixon and Gerald Ford. After his term, his opinion was still sought by many subsequent presidents and many world leaders.

A proponent of Realpolitik, Kissinger played a dominant role in United States foreign policy between 1969 and 1977. During this period, he pioneered the policy of détente with the Soviet Union, orchestrated the opening of relations with the People's Republic of China, and negotiated the Paris Peace Accords, ending American involvement in the Vietnam War. Various American policies of that era, including the bombing of Cambodia, remain controversial to many.

Kissinger is still a controversial figure today. He is the founder and chairman of Kissinger Associates, an international consulting firm.
