Africa's longest serving leaders

Zimbabwe's former president Robert Mugabe, whose death was announced on Friday, was in power for 37 years, but is far from the only African leader to have ruled for so long.

Equatorial Guinea's Teodoro Obiang Nguema is Africa's longest-serving president currently in power after 40 years. Having come to power in a 1979 coup, he was re-elected in 2016 to a fifth seven-year term in his tiny, oil-rich country.

Here is a rundown of the continent's leaders in longevity.
