Luxembourg-Ville. Population: 82,000 (2005).

The Grand Duchy of Luxembourg shares borders to the north and west with Belgium, to the south with France and to the east with Germany. One-third of the country is made up of the hills and forests of the Ardennes, while the rest is wooded farmland. In the southeast is the rich wine-growing valley of Moselle. The capital, Luxembourg-Ville, is built on a rock overlooking the Alzette and Petrusse valleys.

Prime Minister Jean-Claude Juncker since 1995.

Jean-Claude Juncker, of the conservative Christian Social Party, has been Prime Minister since 1995 when his predecessor, Jacques Santer, became President of the European Commission. His party had originally formed a coalition government with the Democratic Party. Following the June 2004 general elections, he formed a coalition with the Socialist Workers Party. In July 2005, Luxembourg's voters backed a proposed EU constitution, already rejected by the French and Dutch.

Handshaking is the normal greeting. The code of practice for visiting someone’s home is similar to other Western European countries: it is acceptable to give gifts or flowers if invited for a meal. Smart-casual dress is widely acceptable, but some dining rooms, clubs and social functions will demand formal attire. Smoking is prohibited where notified and is becoming increasingly unacceptable.
