Because Akrotiri and Dhekelia are UK Sovereign Base Areas (SBAs) in Cyprus, a former British Crown Colony. British Forces Cyprus are stationed there to defend them, and they contain a British listening post, and the only fully fledged RAF station in the Mediterranean, RAF Akrotiri. In addition to the garrison, the UK makes a contribution to the United Nations force in Cyprus. In total, some 3,500 British personnel are based in Cyprus.
Civilian laws are enacted by the British civilian authorities, but are patterned on those of the Republic of Cyprus. Many Cypriots work in the SBAs, mainly for the British authorities or as farmers, or for a few local businesses. But only those Cypriots with a local connection are permitted to live there, such as those who live in Akrotiri village or in the outskirts of villages neighbouring the bases. Also the villages of Xylotymvou and Ormidhia are exclaves of the Republic of Cyprus surrounded by Dhekelia SBA.
The Sovereign Bases in Cyprus are an overseas territory, but instead of having a Governor, like other such territories, it has an Administrator, who, while appointed by the Queen, is responsible to the Ministry of Defence, not to the Foreign and Commonwealth Office.
