David William Donald Cameron (pronunciation: /ˈkæmərən/; born 9 October 1966) is the Prime Minister of the United Kingdom, First Lord of the Treasury, Minister for the Civil Service and Leader of the Conservative Party. He represents Witney as its Member of Parliament (MP).

Cameron studied Philosophy, Politics and Economics (PPE) at Oxford, gaining a first class honours degree. He then joined the Conservative Research Department and became Special Adviser to Norman Lamont, and then to Michael Howard. He was Director of Corporate Affairs at Carlton Communications for seven years.

He was defeated in his first candidacy for Parliament at Stafford in 1997, but was elected in 2001 as the Member of Parliament for the Oxfordshire constituency of Witney. He was promoted to the Opposition front bench two years later, and rose rapidly to become head of policy co-ordination during the 2005 general election campaign. With a public image of a youthful, moderate candidate who would appeal to young voters, he won the Conservative leadership election in 2005.

David (Hebrew: דָּוִד, דָּוִיד, Modern David Tiberian Dāwîḏ; ISO 259-3 Dawid; Strong's Daveed; beloved; Arabic: داوود‎ or داود‎ Dāwūd) was, according to the Hebrew Bible, the second king of the United Kingdom of Israel and, according to the Gospel of Matthew and the Gospel of Luke, an ancestor of Jesus. David is seen as a major Prophet in Islamic traditions. His life is conventionally dated to c. 1040–970 BC, his reign over Judah c. 1010–1003 BC,^{[citation needed]} and his reign over the United Kingdom of Israel c. 1003–970 BC.^{[citation needed]} The Books of Samuel, 1 Kings, and 1 Chronicles are the only sources of information on David, although the Tel Dan stele records "House of David", which some take as confirmation of the existence in the mid-9th century BC of a Judean royal dynasty called the "House of David".

David is very important to Jewish, Christian and Islamic doctrine and culture. In Judaism, David, or David HaMelekh, is the King of Israel, and the Jewish people. Jewish tradition maintains that a direct descendant of David will be the Messiah. In Islam, he is known as Dawud, considered to be a prophet and the king of a nation. He is depicted as a righteous king, though not without faults, as well as an acclaimed warrior, musician, and poet, traditionally credited for composing many of the psalms contained in the Book of Psalms.

In 1996, David Letterman was ranked #45 on TV Guide's 50 Greatest TV Stars of All Time.

Letterman was born in Indianapolis, Indiana. His father, Harry Joseph Letterman (April 1915 – February 1973), was a florist of British descent; his mother Dorothy Letterman (née Hofert, now Dorothy Mengering), a Presbyterian church secretary of German descent, is an occasional figure on the show, usually at holidays and birthdays.

Li Keqiang (born 1 July 1955) is the Executive Vice-Premier of the State Council of the People's Republic of China, the seventh ranked member of the Politburo Standing Committee, the People's Republic of China's de facto highest decision-making body. As Premier Wen Jiabao's top lieutenant, Li's official portfolio includes economic development, price controls, finance, climate change, and macroeconomic management.

Li rose through the ranks of the Communist Youth League. From 1998 to 2004, Li served as the Governor of Henan and the province's CPC party chief, and then the Liaoning party chief, an office that made him first-in-charge in that province. Li is speculated as the likely successor to Wen Jiabao as Premier in the "fifth generation" (Xi-Li Administration) of CPC leadership.

Li Keqiang was born in Dingyuan County, Anhui on 1 July 1955. His father was a local official in Anhui. Li graduated from high school in 1974, during the Cultural Revolution, and was sent for rural labour in Fengyang County, Anhui, where he eventually joined the Communist Party of China and made his way to becoming the party head of the local production team. He was awarded with the honour of Outstanding Individual in the Study of Mao Zedong Thought during this time.
