evidence: Gibraltar is an overseas territory of the United Kingdom and is self-governing in all matters but defense. Its constitution was established by the Gibraltar Constitution Order in 1969, which provided for a House of Assembly consisting of the speaker (appointed by the governor), 15 members elected to four-year terms, and 2 ex-officio members. (A new Constitution Order was approved by referendum in November 2006 and was implemented in January 2007; it renamed the House of Assembly as the Gibraltar Parliament and increased its number of members to 17.) In 1981 Gibraltarians were granted full British citizenship. Gibraltarians age 18 or older and British civilians resident for more than six months are entitled to vote. The governor, appointed by the British sovereign, is the head of the executive Gibraltar Council and appoints the Council of Ministers, composed of the chief minister and other ministers, from the party or coalition of parties that gains a majority of seats in the Gibraltar Parliament. Instead of a city council, one minister is responsible for municipal affairs.
