Gibraltar is a British overseas territory located near the southernmost tip of the Iberian Peninsula overlooking the Strait of Gibraltar. The territory shares a border with Spain to the north. Gibraltar has historically been an important base for the British Armed Forces and is the site of a Royal Navy base. Gibraltar was ceded by Spain to Great Britain in perpetuity in 1713 under the Treaty of Utrecht though Spain requests its return. The British Government has stated it is committed to respecting the wishes of the Gibraltarians, who strongly oppose the idea of annexation along with any proposal for shared sovereignty with Spain (Wikipedia).
