<h1>Nigeria's former president dies at 82 in London after serving as military ruler and democratic leader</h1> Nigeria's former president, who led the country twice as military head and democratic president, died at 82 in London while receiving medical treatment.

Later elected democratically in 2015, he promised to combat corruption and security crises but left office in 2023 amid worsened insecurity, economic recession, and persistent corruption.
