The United Arab Emirates is quitting Opec next month after nearly 60 years - but what exactly is Opec? Opec was formed in 1960 by five countries - Iran, Iraq, Kuwait, Saudi Arabia and Venezuela - to defend the interests of major oil exporters by coordinating production to ensure steady revenue for its members. The UAE said its decision to leave would help it meet growing global energy demand in the long term. But its exit is seen as a blow to the cartel, which oversees oil production and has a major influence on the global prices - with one analyst calling it "the beginning of the end of Opec".
