Alderney is an autonomous dependency of Guernsey, which is a British Crown dependency. It has a population of around 2000 people, and its capital is St. Anne.
Alderney is 3 miles (5 km) long and 1.5 miles (2.4 km) wide and has an area of 3 square miles (8 km2). It lies around 10 miles (15 km) to the west of Normandy, 20 miles (30 km) to the north-east of Guernsey and 60 miles (100 km) from the south coast of Great Britain. It is the closest of the Channel Islands to both France and the United Kingdom.
While Alderney enjoys full autonomy in law, except in matters of foreign affairs and defence, along with the other Channel Islands and the Isle of Man. Under the provisions of a formal agreement between the Government of Alderney and the Government of Guernsey, certain matters have been delegated to Guernsey. These are known as 'the transferred services' and include policing, customs and excise, airport operations, health, education, social services, childcare and adoption. In return for providing the transferred services, Guernsey levies various taxes and duties on Alderney. In addition to the transferred services, both the UK and Guernsey may legislate on other matters with the consent of the States of Alderney.
