Dato' Sri Haji Mohammad Najib bin Tun Haji Abdul Razak (born 23 July 1953) is a Malaysian politician who has been the sixth Prime Minister of Malaysia since 2009. He previously held the post of Deputy Prime Minister from 7 January 2004 until he succeeded Tun Abdullah Ahmad Badawi as Prime Minister on 3 April 2009. Najib is President of the United Malays National Organisation (UMNO). He is the son of Malaysia's second prime minister, Tun Abdul Razak and the nephew of Malaysia's third prime minister, Tun Hussein Onn. Najib is also the Minister of Finance.

Najib succeeded Abdullah at a time after his ruling coalition, the Barisan Nasional, lost its long held two-thirds majority in parliament to the opposition led by former Deputy Prime Minister Anwar Ibrahim in the 2008 parliamentary election. Since then Najib has tried to build a moderate image for himself and the UMNO through the 1Malaysia campaign.

Born 23 July 1953, in Kuala Lipis, Pahang, Najib is the eldest of Prime Minister Abdul Razak's six sons, and the nephew of Hussein Onn, Malaysia’s third Prime Minister. His younger brother, Dato' Seri Mohd Nazir Abdul Razak, runs the country's second-largest lender, Bumiputra-Commerce Holdings Bhd. Najib is also one of the Four Noblemen of the Pahang Darul Makmur (Royal Court) by virtue of his inherited title as the Orang Kaya Indera Shahbandar. He received his primary and secondary education at St. John's Institution, Kuala Lumpur. He later attended Malvern College in Worcestershire, England, and subsequently went to the University of Nottingham, where he received a bachelor's degree in industrial economics in 1974. Najib Razak returned to Malaysia in 1974 and entered the business world, serving briefly in Bank Negara (Central Bank) and later with Petronas (Malaysia's national oil company) as a public affairs manager.

The Four Corners is a region of the United States consisting of the southwestern corner of Colorado, northwestern corner of New Mexico, northeastern corner of Arizona and southeastern corner of Utah. The Four Corners area is named after the quadripoint where the boundaries of the four states meet, where the Four Corners Monument is located. The majority of the Four Corners region is part of semi-autonomous indigenous American Indian nations, the largest of which is the Navajo Nation, followed by Hopi, Ute and Zuni Indian nations. The Four Corners region is part of a larger region known as the Colorado Plateau and is mostly rural, rugged and arid. In addition to the monument, commonly visited areas within Four Corners include Monument Valley, Mesa Verde National Park and Canyon de Chelly National Monument. The most populous city in the Four Corners region is Farmington, New Mexico, followed by Durango, Colorado.

The United States first acquired the area now called Four Corners from Mexico after the Mexican–American War in 1848. In 1863 Congress created Arizona Territory from the western part of New Mexico Territory. The boundary was defined as a line running due south from the southwest corner of Colorado Territory, which had been created in 1861. This was an unusual act of Congress, which almost always defined the boundaries of new territories as lines of latitude or longitude, or following rivers. By defining one boundary as starting at the corner of another Congress ensured the eventual creation of four states meeting at a point, regardless of the inevitable errors of boundary surveying. The area was first surveyed by the U.S. Government in 1868 as part of an effort to make Colorado Territory into a state, the first of the Four Corners states formed. The first marker was placed at the spot in 1912. The first Navajo tribal government was established in 1923 to regulate an increasing number of oil exploration activities on Navajo tribal lands.
