Former Nigerian President Muhammadu Buhari, who led the country twice as a military head of state and a democratic president, has died aged 82.

But Nigeria refused to bend to Mr Buhari’s will. Almost 500 politicians and businessmen were arrested for corruption and sent to jail by military tribunals. A new currency was issued to flush out the stashes piled floor to ceiling in the homes of the elite. For many military men this purge was too close for comfort—and too uncompromising.

When Muhammadu Buhari was elected in 2015, on his fourth attempt, he became the first opposition candidate to win a presidential election.
