Buhari, a former military general who campaigned on rooting out government corruption, has died at age 82, the presidential press office said in a statement on Sunday.

Nigeria's President Muhammadu Buhari, who has died age 82 in a London clinic, was a former military ruler and self-styled converted democrat who returned to power through elections but struggled to convince Nigerians he could deliver on the change he promised.

Muhammadu Buhari was laid to rest in his hometown, Daura, in northern Nigeria. He leaves behind a mixed legacy, having been both a former military leader and a democratically elected president.
