The UAE's long-time de facto ruler Sheikh Mohamed bin Zayed Al Nahyan was elected as president on Saturday, official media said, a day after the death of former leader Sheikh Khalifa.

Sheikh Mohamed was elected by the Federal Supreme Council, WAM news agency said, becoming the ruler of the oil-rich country founded by his father in 1971.

Sheikh Mohamed, often known as 'MBZ', met members of the Federal Supreme Council, made up of rulers of the UAE's seven emirates, as the oil-rich country enters a period of mourning for his half-brother Sheikh Khalifa.
