Yei is a city in the central south of Sudan and a local headquarters of the SPLA for Central Equatoria state, formerly part of the province of Equatoria. The name Yei was born out of the city's proximity to the river Yei where in 1915 a small clinic was set up by Britishmissionaries. The city dwellers prefer to call it small London because of its cosmopolitan nature.
