The 23rd G8 summit was held from June 20 to 22, 1997 in Denver, Colorado, United States. The venue was the newly constructed Denver Public Library in downtown Denver. The locations of previous G8 summits to have been hosted by the United States include: San Juan, Puerto Rico (1976); Williamsburg, Virginia (1983); and Houston, Texas.

The Group of Seven (G7) was an unofficial forum which brought together the heads of the richest industrialized countries: France, Germany, Italy, Japan, the United Kingdom, the United States and Canada starting in 1976. The G8, meeting for the first time in 1997, was formed with the addition of Russia. In addition, the President of the European Commission has been formally included in summits since 1981. The summits were not meant to be linked formally with wider international institutions; and in fact, a mild rebellion against the stiff formality of other international meetings was a part of the genesis of cooperation between France's President Giscard d'Estaing and West Germany's Chancellor Helmut Schmidt as they conceived the initial summit of the Group of Six (G6) in 1975.

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.
